The next generation of lidar systems needs to adapt to variable environments with broadened bandwidth for increased resolution. Due to their digital components, conventional lidar systems, especially imaging lidar systems, suffer from limited detector bandwidth and sampling frequency. However, photonics devices can provide a reliable technical solution with high precision and ultra-broad bandwidth. This paper presents a photonic signal processing structure for a phase-coded lidar system. Two acousto-optic modulators (AOMs) are adopted in the proposed architecture. One is used for phase-coded laser signal modulation, and the other is used for demodulation. The echo laser signal is directed to the AOM performing demodulation before the sampling of the detector, accomplishing the multiplication of the echo laser signal and the electric reference signal. The detector is controlled to accumulate the demodulated laser signal. The AOM and detector transfer the correlation calculation from electrical signals processing to photonic signals processing. This photonics-based structure greatly decreases the sampling frequency of the detector without extending the width of the laser pulses, which achieves high resolution with low sampling speed. Photonic signal processing has the promising potential of simultaneously processing signals of multiple pixels. It is going to be an effective solution for imaging lidar systems to increase resolution with available low-cost devices.

Three physical elements are missing from the conventional formalism of quantum photonics: (1) the quantum Rayleigh spontaneous and stimulated emissions; (2) the unavoidable parametric amplification; and (3) the mixed time-frequency spectral structure of a photonic field which specifies its duration or spatial extent. As a single photon enters a dielectric medium, the quantum Rayleigh scattering prevents it from propagating in a straight-line, thereby destroying any possible entanglement. A pure dynamic and coherent state composed of two consecutive number states, delivers the correct expectation values for the number of photons carried by a photonic wave front, its complex optical field, and phase quadratures. The intrinsic longitudinal and lateral field profiles associated with a group of photons for any instantaneous number of photons are independent of the source. These photonic properties enable a step-by-step analysis of the correlation functions characterizing counting of coincident numbers of photons or intensities with unity visibility interference, spanning the classical and quantum optic regimes.

In this study, an artificial neural network that can predict the band structure of 2-D photonic crystals is developed. Three kinds of photonic crystals in a square lattice, triangular lattice, and honeycomb lattice and two kinds of materials with different refractive indices are investigated. Using the length of the wave vectors in the reduced Brillouin zone, band number, r/a ratio, and the refractive indices as the dataset, the desired ANN is trained to predict the eigenfrequencies of the photonic modes and depict the photonic band structures with a correlation coefficient greater than 0.99. By increasing the number of neurons in the hidden layer, the correlation coefficient can be further increased over 0.999.

Context. Infrared heterodyne interferometry has been proposed as a practical alternative for recombining a large number of telescopes over kilometric baselines in the mid-infrared. However, the current limited correlation capacities impose strong restrictions on the sensitivity of this appealing technique. Aims. In this paper, we propose to address the problem of transport and correlation of wide-bandwidth signals over kilometric distances by introducing photonic processing in infrared heterodyne interferometry. Methods. We describe the architecture of a photonic double-sideband correlator for two telescopes, along with the experimental demonstration of this concept on a proof-of-principle test bed. Results. We demonstrate the a posteriori correlation of two infrared signals previously generated on a two-telescope simulator in a double-sideband photonic correlator. A degradation of the signal-to-noise ratio of 13%, equivalent to a noise factor NF = 1.15, is obtained through the correlator, and the temporal coherence properties of our input signals are retrieved from these measurements. Conclusions. Our results demonstrate that photonic processing can be used to correlate heterodyne signals with a potentially large increase of detection bandwidth. These developments open the way to photonic processing of wide bandwidth signals for mid-infrared heterodyne interferometry, in particular for a large number of telescopes and for direct imager recombiners.

Quantum correlations of higher-dimensional systems are an important content of quantum information theory and quantum information application. The quantification of quantum correlation of high-dimensional quantum systems is crucial, but difficult. In this paper, using the second-order nonlinear optical effect and multiphoton interference enhancement effect, we experimentally implement the photonic qutrit states and demonstrate the spin-1 information entropic inequality for the first time to quantitative quantum correlation. Our work shows that information entropy is an important way to quantify quantum correlation and quantum information processing.

Single-photon sources are one of the essential building blocks for the development of photonic quantum technology. In terms of potential practical application, an on-demand electrically driven quantum-light emitter on a chip is notably crucial for integrating photonic integrated circuits. Here, we propose functionalized single-walled carbon nanotube field-effect transistors as a promising solid-state quantum-light source by demonstrating photon antibunching behavior via electrical excitation. The sp3 quantum defects were formed on the surface of (7, 5) carbon nanotubes by 3,5-dichlorophenyl functionalization, and individual carbon nanotubes were wired to graphene electrode pairs. Filtered electroluminescent defect-state emission at 77 K was coupled into a Hanbury Brown and Twiss experiment setup, and single-photon emission was observed by performing second-order correlation function measurements. We discuss the dependence of the intensity correlation measurement on excitation power and emission wavelength highlighting the challenges of performing such measurements while simultaneously analyzing acquired data. Our results indicate a route toward room-temperature electrically-triggered single-photon emission.

Abstract The promise of artificial intelligence (AI) to process complex datasets has brought about innovative computing paradigms. While recent developments in quantum-photonic computing have reached significant feats, mimicking our brain’s ability to recognize images are poorly integrated in these ventures. Here, I incorporate orbital angular momentum (OAM) states in a classical Vander Lugt optical correlator to create the holographic photonic neuron (HoloPheuron). The HoloPheuron can memorize an array of matched filters in a single phase-hologram, which is derived by linking OAM states with elements in the array. Successful correlation is independent of intensity and yields photons with OAM states of lℏ, which can be used as a transmission protocol or qudits for quantum computing. The unique OAM identifier establishes the HoloPheuron as a fundamental AI device for pattern recognition that can be scaled and integrated with other computing platforms to build-up a robust neuromorphic quantum-photonic processor.

For any communication, the conveyed information must be carried by some physical system. If this system is a quantum system rather than a classical one, its behavior will be governed by the laws of quantum mechanics. Hence, the properties of quantum mechanics, such as superpositions and entanglement, are accessible, opening up new possibilities for transferring information. The exploration of these possibilities constitutes the field of quantum communication. The key ingredient in quantum communication is the qubit, a bit that can be in any superposition of 0 and 1, and that is carried by a quantum state. One possible physical realization of these quantum states is to use single photons. Hence, to explore the possibilities of optical quantum communication, photonic quantum states must be generated, transmitted, characterized, and detected with high precision. This thesis begins with the first of these steps: the implementation of single-photon sources generating photonic qubits. The sources are based on photon-pair generation in nonlinear crystals, and designed to be compatible with fiber optical communication systems. To ensure such a compatibility and to create a high-quality source, a theoretical analysis is made, optimizing the coupling of the photons into optical fibers. Based on the theoretical analysis, a heralded single-photon source and a two-crystal source of entangled photons-pairs are experimentally implemented. The source of entangled photons is further developed into a compact source with a narrow bandwidth compatible with standard telecommunication wavelength-division multiplexers, and even further developed to a more stable one-crystal source. The sources are to be used for quantum communication in general and quantum cryptography in particular. Specifically, a heralded single-photon source is implemented and then used for a full test of a decoy-state quantum cryptography protocol.

Annotation:
A spatial domain Optimal Trade-off Maximum Average Correlation Height (SPOT-MACH) filter is proposed in this thesis. The proposed technique uses a pre-defined fixed size kernel rather than using estimation techniques. The spatial domain implementation of OT-MACH offers the advantage that it does not have shift invariance imposed on it as the kernel can be modified depending upon its position within the input image. This allows normalization of the kernel and allows inclusion of a space domain non-linearity to improve performance. The proposed SPOT-MACH filter can be used to maximize the height of the correlation peak in the presence of distortions of the training object and provide resistance to background clutter. One of the major characteristics of the SPOT-MACH filter is that it can be tuned to maximize the height and sharpness of the correlation peak by using trade-offs between distortion tolerance, peak sharpness and the ability to suppress clutter noise. A number of non-parametric local regression techniques offer a simplified approach to pattern recognition problems which employ linear filtering using low pass filters designed using moving window local approximations. In most of these cases the algorithms search for a region of interest near the point of estimation for various prevailing conditions which fit the required criteria. These estimates are calculated for a defined window size which is determined as being the largest area within which the estimators do not widely vary from the criteria. The only drawback in this approach is that the window size is directly proportional to the required computational resources and would adversely affect the performance of the system if the moving window size is not proportionate to the resources. The proposed filter employs an optimization technique using low-pass filtering to highlight the potential region of interests in the image and then restricts the movement of the kernel to these regions to allow target identification and to use less computational resources. Also another optimization technique is also proposed which is based on an entropy filter which measures the degree of randomness between two changing scenes and would return the area where change has occurred i.e. the target object might be present. This approach gives a more accurate region of interest than the low-pass filtering approach. Apart from the software based optimization approaches two hardware based enhancement techniques have also been proposed in this thesis. One of the approaches employs Field Programmable Gate Array (FPGA) to perform correlation process employing the inbuilt multipliers and look up tables and the other one uses Graphical Processing Unit (GPU) to do parallel processing of the input scene. Also in this thesis a detailed analysis of SPOT-MACH has been carried out by comparing with popular feature based techniques like Scale Invariant Feature Transform (SIFT) and a comparison matrix has been created. The proposed filter uses a two-staged approach using speed optimizations and then detection of targets from input scenes. Both visible and Forward Looking Infrared (FLIR) imagery data sets have been used to test the performance of filter.

L'émission dans le moyen infrarouge des disques protoplanétaires et des enveloppes stellaires contient de précieuses informations sur leur composition en poussières et en gaz, ainsi que sur les phénomènes qui se produisent au voisinage des étoiles jeunes, comme la formation de planètes terrestres. Pour étudier en détail la physique de ces systèmes dynamiques, il faudrait une résolution inférieure à l’unité astronomique sur des objets à une centaine de parsecs. Une telle résolution ne peut être obtenue que par interférométrie à très longue base car elle correspond à des diamètres de télescope kilométriques. La création d'un interféromètre dans le moyen infrarouge avec de longues lignes de base a été identifiée par l’initiative Planet Formation Imager comme la prochaine étape majeure pour contraindre les modèles théoriques de formation planétaire.Actuellement, les interféromètres infrarouges les plus sensibles, comme MATISSE et GRAVITY au VLTI, reposent sur la recombinaison directe de quelques télescopes. Une telle méthode est difficilement extensible à un grand nombre de télescopes sur des lignes de base kilométriques en raison des pertes en transmission et de l'encombrement des infrastructures. L'interférométrie hétérodyne, largement utilisée dans le domaine radio, pourrait représenter une alternative à l'interférométrie directe car elle ne nécessite pas de recombiner physiquement la lumière des télescopes. Elle repose sur la détection hétérodyne du champ électrique de la lumière à chaque télescope, avec un oscillateur local référencé en phase et des détecteurs moyen infrarouge à grande bande passante. Les signaux résultants sont transmis à un corrélateur qui en extrait les observables interférométriques. Cependant, l'interférométrie hétérodyne moyen infrarouge souffre d'une sensibilité réduite en raison du bruit quantique inhérent à la détection hétérodyne. Pour détecter des objets peu lumineux, des efforts considérables sont nécessaires afin de résoudre les défis techniques et technologiques qui limitent la sensibilité d'un tel système.Mon doctorat se concentre sur les aspects de corrélation et de détection moyen infrarouge de l'interférométrie hétérodyne. L'aspect corrélation consiste à mettre en place et à caractériser le banc de démonstration HIKE (Heterodyne Interferometry Kilometric Experiment) de l'IPAG, à Grenoble. Ce banc utilise un corrélateur photonique analogique constitué de composants télécoms à 1,5 micromètre pour corréler des signaux moyen infrarouge à 10 micromètres, avec des bandes passantes de l'ordre du gigahertz. Une telle expérience de corrélation photonique de signaux moyen infrarouge est une première mondiale. J’ai développé une méthodologie pour caractériser les niveaux de bruit dans le système afin d’identifier les éléments qui dégradent la mesure de la visibilité interférométrique. Mes résultats montrent que le niveau de bruit associé au corrélateur photonique ne dégrade pas le rapport signal sur bruit du système. Ainsi, la corrélation photonique peut être utilisée comme alternative à la corrélation numérique, habituellement utilisée en radioastronomie, mais lourde en calculs numériques.Actuellement, la principale limite de notre système vient des détecteurs commerciaux utilisés pour la détection hétérodyne. J'ai donc étudié la possibilité de remplacer nos détecteurs par des détecteurs à puits quantiques à large bande passante. Ce travail a été réalisé en collaboration avec l'équipe QUAntum physics and Devices (QUAD) du LPENS à Paris, où j'ai caractérisé des détecteurs moyen infrarouge à puits quantiques de type QWIP et QCD utilisant des métamatériaux. En théorie, les larges bandes passantes de ces détecteurs permettraient de détecter plus de signal astronomique. Cependant, malgré des progrès récents, l’efficacité quantique de ce type de détecteurs reste actuellement trop faible pour notre application d’interférométrie hétérodyne. De nouvelles avancées technologiques sont nécessaires
The mid-infrared emission from protoplanetary disks and stellar envelopes carries precious information about their dust and gas composition and the phenomena occurring in the vicinity of young stars, like the formation of terrestrial planets. To study the underlying physics of such dynamical systems, astronomical instruments require a resolution below the astronomical unit on objects a hundred parsecs away. This resolution can only be achieved with long-baseline interferometry because it corresponds to telescope diameters of a few kilometres. The Planet Formation Imager initiative has identified the creation of a mid-infrared interferometric array with a large number of telescopes as the next major step to constrain the theoretical models that describe planetary formation.Currently, the most sensitive infrared interferometers, like the MATISSE and GRAVITY instruments at VLTI, rely on the direct recombination of light from several telescopes. This method is hardly scalable to many telescopes on kilometric baselines because of transmission losses and the bulkiness of the infrastructures. Heterodyne interferometry, which is widely used in radio-interferometry, has been identified as a possible alternative to direct interferometry in the mid-infrared because it does not require recombining the light from all telescopes physically. Instead, it relies on the heterodyne detection of the astronomical electric field with a phase-referenced local oscillator (a laser) and detecting the intermediate frequency with high-bandwidth detectors. The resulting signals are transmitted to a correlator whose role is to retrieve the interferometric observables from them. However, mid-infrared heterodyne interferometry suffers from reduced sensitivity because of the inherent quantum noise in heterodyne detection. Therefore, to detect weak astronomical objects, considerable efforts must be put to solve the technical and technological challenges that further limit the sensitivity of an heterodyne system.My PhD thesis concentrates on the correlation and detection aspects of mid-infrared heterodyne interferometry. The correlation aspect consists of setting up, operating, and characterising the HIKE (Heterodyne Interferometry Kilometric Experiment) demonstration bench at IPAG, Grenoble. The bench uses an analogue photonic correlator built with commercial telecom components at 1.5 micrometres wavelength to correlate mid-infrared signals at 10 micrometres wavelength with gigahertz bandwidths. Such a set-up is a world premiere. I have developed a methodology to characterise the noise levels inside the system to identify the top offenders that hamper the measurement of interferometric visibility, and implement solutions to improve the sensitivity of the bench. My results show that the noise level associated with the photonic correlator is sufficiently low not to deteriorate the signal-to-noise ratio of the system. Hence, photonic correlation is sensitive enough to be used by heterodyne interferometry as an alternative to the computationally heavy digital correlation that is often used for radio heterodyne interferometry.The current top offenders of our system are the commercial mid-infrared detectors that are used for heterodyne detection. Therefore, to improve the sensitivity of the bench, I have studied the possibility of replacing our detectors with high-bandwidth mid-infrared quantum well detectors. This work has been done in collaboration with the QUAD team at LPENS, Paris, where I have characterised metamaterial enhanced Quantum Well Infrared Photodetectors (QWIP) and Quantum Cascade Detectors (QCD). The high bandwidths of these detectors would represent a significant advantage to detect a larger chunk of the astronomical signal. However, despite recent progress, their quantum efficiencies currently remain too low to obtain a game-changing sensitivity improvement in heterodyne interferometry. Further improvement in the technology is required

The plasma membrane separates the cell from its environment. But it is more than a barrier any cell has to communicate with the outside world. Therefore the plasma membrane plays a prime role in transferring and exchanging information. However, the biological study of the plasma membrane remains difficult due to the extraordinary complexity of it organization.My thesis is a part of an effort to develop new experimental approaches to explore more specifically the organization and the role of the plasma membrane in the signal transduction mechanisms. Two major aspects were followed: the first one concerns the description of the dynamics of membrane organization and of molecular interactions, the second concerns the inter-connectivity and signal transduction between a cell and other biological partners.This manuscript is composed of several parts. The first chapter briefly introduces the biological questions that I tried to answer. In the second chapter, I present the methods commonly used to study the membrane with a dynamic perspective. Additionally, I include a series of observations that I made on the EGF receptor diffusion. The third chapter is devoted to the fluorescence cross-correlation technique to study the assembly of the EGFR. In the fourth part, I demonstrate how scientific collaborations at the interface between biology and physics have led to the development of innovative solutions on a holographic optical tweezers system. I present applications of this system in different biological models. Finally, I conclude this thesis with a brief discussion about my technological and biological results

Quantum mechanics has led to the biggest technological breakthroughs of last century. However, many paradoxes still remain in the foundations of quantum theory. In this research we study one effect that leads to such paradoxes; quantum correlations. Quantum nonlocality refers to the set of quantum correlations that are not explainable using local models. It is quantum nonlocality that has troubled physicists since the inception of quantum theory nearly 100 years ago. However, these nonlocal quantum correlations offer a range of advantages in quantum information tasks. For example, quantum key distribution and quantum computing are two tasks that are powered by quantum correlations. For this reason a wide range of quantum correlations are studied experimentally in this research. These include: entanglement, EPR-steering, Bell nonlocality and bilocality. We study these correlations using the framework of quantum information, using single photons as our chosen quantum information carriers. The first quantum correlation tested in this research is EPR-steering. EPR-steering is the application of the EPR-paradox to a quantum information task. We implement three different experiments on EPR-steering. By studying the properties of the quantum information task we find that: EPR-steering is more robust to depolarisation noise than Bell-nonlocality; EPR-steering is absolutely loss tolerant; and tests of EPR-steering are easier to carry out, than tests of Bell nonlocality, but harder to implement compared to tests of non-separability. As a result of these three findings we experimentally show that EPR-steering can be demonstrated on Belllocal states, we close the detection loophole in a photonic test of quantum nonlocality, and we discover and implement maximally parsimonious tests of non-separability, EPR-steering and Bell nonlocality.

Annotation:
Quantum particles show a distinct behaviour compared to classical particles. The fundamental principles of superposition and entanglement lead to interference effects, which often seem to contradict common sense trained by classical physics. Within the emerging field of quantum information and computation techniques for harnessing these quantum interference effects for information processing tasks have been developed. A complex interference phenomenon, which is at the heart of theoretical and experimental quantum information, is quantum walks. It describes the movement of quantum mechanical particles within a discretised space and finds applications in designing quantum algorithms and for implementing quantum simulations. This thesis explores multi-photon interference of identical and entangled particles in physically implemented quantum walk structures. In particular, we realise continuous-time quantum walks, using single photons propagating in integrated waveguide arrays. Here, the evolution is given by the continuous evanescent coupling of the photons between neighbouring waveguides. We demonstrate two-photon quantum walks on a one-dimensional line, where we can observe the time evolution by measuring the output distribution of waveguide arrays with varied lengths. Within this work, we investigate boundary conditions and coherence of the evolution. Additional to this, we employ waveguides, laser-written in glass substrate, implementing a quantum walk on a two-dimensional graph structure. We show quantum interference effects between two photons, which are unique to this two-dimensional structure. In a third experiment, we measure the quantum walk of up to five photons. We compare the output statistics of this structured unitary with the output of a random circuit and we construct a metric for verifying quantum interference. Furthermore, we show, that quantum correlations of entangled particles prevail in a noisy environment and .allow the construction of an entanglement witness. Finally, we utilise entanglement for quantum statistics simulations. Here, we can simulate quantum statistics effects, such as Pauli-exclusion.
