Abstract:
In this paper, a time-domain fast gated near-infrared spectroscopy system is presented. The system is composed of a fiber-based laser providing two pulsed sources and two fast gated detectors. The system is characterized on phantoms and was tested in vivo, showing how the gating approach can improve the contrast and contrast-to-noise-ratio for detection of absorption perturbation inside a diffusive medium, regardless of source-detector separation.

Abstract:
Les nanolasers PhC suscitent de plus en plus d'attention en raison de leur capacité unique à manipuler et à confiner la lumière à une très petite échelle. Leur empreinte réduite et leur seuil bas en font des candidats idéaux pour la réalisation de connexions optiques, répondant ainsi à la demande croissante en matière de vitesse de transmission des données et de consommation d'énergie. De plus, leur géométrie singulière permet de contrôler leurs propriétés d'émission spontanée. Cela révèle l'unicité des nanolasers PhC d'un point de vue fondamental, soulignant leur potentiel à servir de sujets de recherche novateurs dans l'interaction lumière-matière. Malgré ces avantages, une caractérisation de leur émission et de leurs propriétés dynamiques fait toujours défaut, en raison des limitations actuelles des capacités de détection aux longueurs d'onde infrarouges.Dans cette thèse, j'ai développé une technique de détection à porte temporelle basée sur FWM, pour mesurer la réponse ultra-rapide des nanolasers 1D. En étudiant attentivement l'interaction entre les non-linéarités et la dispersion, il a été possible d'atteindre une sensibilité élevée de quelques photons et une résolution de 2 ps. Des améliorations supplémentaires de la sensibilité, jusqu'à moins d'une détection de photon, sont prévues en utilisant des puissances de pompe plus élevées. Cela peut ouvrir la voie à l'étude des statistiques des photons et des effets quantiques au cœur du régime quantique.Les profils des nanolasers 1D présentent un début très rapide de l'émission et une décroissance longue, compatible avec un facteur β de 0,12 et une durée de vie du photon de 20 ps. Une nouvelle approche pour obtenir les valeurs de ces deux paramètres contrôlant la dynamique du laser a été développée : elles ont été directement extraites de la réponse ultra-rapide des nanolasers, au lieu de se baser uniquement sur des mesures à l'état stationnaire telles que la courbe S, qui, dans de nombreux cas, peuvent conduire à des estimations inexactes en raison de l'interdépendance de ces paramètres. La réponse dynamique des nanolasers 1D est compatible avec une vitesse maximale de modulation d'environ 30 GHz, répondant à l'exigence de sources laser ultra-compactes à faible seuil pour les circuits intégrés photoniques et les communications optiques.La haute sensibilité et résolution de la technique nous ont permis de mesurer, pour la première fois à notre connaissance, une conversion de longueur d'onde adiabatique de photons avec un décalage de longueur d'onde aussi important que 1,2 nm. Cela montre le potentiel de la technique dans l'étude des dynamiques ultra-rapides aux longueurs d'onde NIR
PhC nanolasers are receiving more and more attention due to their unique capacity to manipulate and confine light at a very small scale. Their small footprint and low thresholds make them ideal candidates for realizing optical interconnects, thus addressing the increasing demands for data transmission speed and power consumption. Moreover, their singular geometry enables the control of their spontaneous emission properties. This reveals PhC nanolasers' uniqueness from a fundamental point of view, highlighting their potential to serve as candidates for novel research in light-matter interaction. Despite these advantages, a characterization of their emission and their dynamical properties is still missing, due to the current limitations of the detection capabilities at infrared wavelengths.In this thesis, I have developed a time gating detection technique based on FWM, to measure the ultra fast response of 1D nanolasers. By carefully studying the interplay between nonlinearities and dispersion, it was possible to reach a high sensitivity of a few photons and a resolution of 2 ps. Further improvements in sensitivity, down to less than a photon detection, is predicted by employing higher gate powers. This can open the way to study photon statistics and quantum effects deep in the quantum regime.The profiles of 1D nanolasers feature a very fast onset of the emission and a long decay, compatible with a β factor of 0.12 and a photon lifetime of 20 ps. A novel approach to obtaining the values of these two parameters controlling laser dynamics has been developed: they have been directly retrieved from the%The manner in which these two parameters controlling laser dynamics have been obtained constitutes a novel approach, as they have been directly retrieved from theultra-fast response of nanolasers, instead of solely relying on steady state measurements such as the S curve, which, in many cases, can lead to inaccurate estimations due to the interdependence of these parameters. The dynamical response of 1D nanolasers is compatible with a maximum modulation speed of around 30 GHz, fullfiling the requirement for low threshold ultra compact laser sources for photonic integrated circuits and optical communications.The high sensitivity and resolution of the technique allowed us to measure for the first time, to the best of our knowledge, an adiabatic wavelength conversion of photons with a wavelength shift as large as 1.2 nm. This shows the potential of the technique in studying ultra fast dynamics at NIR wavelengths

Abstract:
Un des objectifs du Femtomagnetisme est de contrôler l’aimantation des matériaux avec des impulsions laser femtoseconde. Il a été démontré qu’une réponse magnéto-optique (MO) cohérente a lieu avant la thermalisation des populations de spins dans une configuration pompe-sonde MOKE. Elle résulte du couplage cohérent spin-photon dû à l’interaction spin-orbite. Une description simplifiée de cet effet a été faite en tenant compte d’un système à huit niveaux couplés au champ laser. La cohérence MO est définie par le temps de déphasage dépendent du champ T2MO. Dans ce travail, il est montré que la réponse MO cohérente d’un grenat dopé au bismuth peut être mesurée directement avec différentes configurations de mélange à quatre ondes MO. L’importance de connaître la phase spectrale de l’impulsion pour obtenir T2MO a été étudié. Avec des impulsions de 10fs dans le proche infra-rouge, une mesure de T2MO donne (2.8+/-1)fs, c. à d., du même ordre de grandeur que le temps de déphasage des charges
One of the goals of Femtomagnetism is to manipulate the magnetization of materials using femtosecond optical pulses. It has been shown in ferromagnetic films that a magneto-optical (MO) coherent response takes place before the thermalization of the spins populations in a pump and probe MOKE experiment. It results from the coherent spin-photon coupling mediated by the spin-orbit interaction. A simplified description of this effect has been made by considering an eight-level system coupled with the laser field. The MO coherence can be defined by the magnetic field dependent dephasing time T2MO. In the present work, it is shown that the coherent MO response of a bismuth-doped garnet can be directly measured in different degenerated MO four-wave mixing configurations. The importance of well-knowing the spectral phase of the pulse to measure T2MO was studied. Using 10fs near infra-red pulses, T2MO was shown to be (2.8+/-1)fs that is of the same order of the charges dephasing time

Abstract:
Beginning with the discovery of graphene, two-dimensional materials have amassed a strong interest. Like graphene, transition metal dichalcogenides (TMDs) can be coaxed into atomically thin sheets which have some impressive properties. Unlike graphene, TMDs also has a change in their electronic band structure causing an indirect band gap to a direct gap transition in its monolayer form. Additionally, these materials lose their inversion symmetry as a monolayer. These unique properties make TMDs a strong candidate for being used in optoelectronic and valleytronic devices. In order for these devices to be successful, the optical properties of TMDs must be thoroughly understood. Due to this class of material's strong Coulomb interaction, the optical properties are dominated by excitons, a quasiparticle made up of an electron-hole pair. Therefore, the success of these devices relies, in part, on understanding and manipulating excitons. One key parameter of excitons is their dephasing rate which characterizes the lifetime of the coherent superposition of two states (i.e. how the coherence decays which is caused by excitons interacting with their environment). In this work, two optical properties are investigated: (1) How the linear absorption of the TMDs A-exciton peak varies as the material increases in thickness. By looking at how the absorption varies by sample thickness, the interaction between emitters can be understood. Experimental results for the diamagnetic shift are presented which are used to determine the lateral excitonic size. Through theoretical calculations, based on the semiconductor Maxwell-Bloch equations, additional insight into the radiative coupling of the systems are obtained. (2) How the coherence prole of the exciton changes in the presence of an external magnetic eld and specic valley excitation. By varying the polarization scheme in the four wave mixing measurement, specic valley excitation can be selected, allowing for insight into the dephasing mechanisms. By applying an external magnetic eld, the energy levels of the electron and hole can be discretized and the corresponding eects on the system's coherence seen. In conjunction with time-dependent density function theory calculations and the experimental results, a deeper understanding of exciton dynamics and multi-exciton complexes was obtained. Finally, a new system is proposed in which complex spectroscopic techniques can be performed on micron sized samples as well as devices in the presence of an external magnetic eld at cryogen temperatures. This system will allow for the investigation of the optical properties of stacked monolayers (heterostructures) as well as devices.

Abstract:
Time-resolved four-wave mixing (TRFWM) studies have been carried out on sublimated films of the neodymium phthalocyanine dimer Pc[superscript 2-Nd[superscript III]Pc[superscript point], the cerium porphyrin phthalocyanine sandwich mixed heterodimer Pc[superscript 2-]Ce[superscript IV]TPP[superscript 2-], the cerium porphyrin phthalocyanine symmetric trimer TPP[superscript 2-]Ce[superscript III]Pc[superscript 2-]Ce[superscript III]TPP[superscript 2-], the neodymium porphyrin phthalocyanine trimer Pc[superscript 2-]Nd[superscript III]TPP[superscript 2-]Nd[superscript III]Pc[2-], and Langmuir-Blodgett films of the cobalt porphyrin phthalocyanine mixed dimer CoPC [subscript 22][superscript 4+] / H[subscript 2]PcTS [subscript 4-]. In this work, we have presented a number of novel results: the first non-degenerate time-resolved four-wave mixing (NDTRFWM) experiment on a sublimated film, the first observation and identification of the diffusion contribution to the degrating process, the first observation and identification of photorefractive effect in an organic multimer thin film, and the first observation and identification of a correlated phonon mode shifting phenomenon. The absolute values of the third-order nonlinear optical susceptibility [chi superscript (3)] of the samples have been determined by comparing the third-order nonlinear optical responses of the samples with those of a slide of reference fused quartz under the same experimental conditions. It is shown that TRFWM is a very useful, very sensitive and very powerful tool to investigate the dynamics of the third-order nonlinear optical processes in a medium, especially those that can not be detected by transient absorption and other means of probing nonlinear optical properties. Through this work, it can be seen that lanthanide porphyrin phthalocyanine dimer/heterodimer trimer/heterotrimer systems could be a new family of organic materials most promising for the investigation and the applications of photorefractive effect. They are very versatile and have a great potential as nonlinear optical materials.

Abstract:
The present work would like contribute to the research in this area, by offering some results on the optical properties, disorder and non-linear effects on wave propagation in semiconductor-based two-dimensional photonic crystal waveguides. The aim is to lead the reader from the basic concepts of photonic crystals (Chapter 1), up to the properties of a 2D photonic crystal (Chapter 2) and the defect line induced waveguide in a 2D photonic crystal (Chapter 3). The propagation properties, the unusual dispersion relation, and the particular regime, known as Slow Light regime, will be analyzed depthly. Particular attention is devoted to model the extrinsic disorder induced by the fabrication process and its impact on the propagation properties of the waveguide (Chapter 4). In the last two chapters, the focus will be on two techniques to characterize photonic crystal waveguides. The first tool is the Time-Wavelength Reflectance Map (Chapter 5), developed with Thales Research and Technology, Paris, France, that permits to evaluate the propagation properties of the waveguide as function of the wavelength showing us a deep physical insight for understanding the role of disorder induced scattering and how it is connected to dispersion. In Chapter 6, a laboratory setup will be presented, based on the Heterodyne Pump-Probe technique, used in a set of experiments at DTU Fotonik, with the main objective to investigate on the Slow Light regime.
Questo lavoro di tesi presenta alcuni nuovi risultati sulle proprietà ottiche e sugli effetti del disordine sulla propagazione in guide d'onda a cristallo fotonico bidimensionale. Lo studio parte dai concetti di base dei cristalli fotonici (Cap. 1), quali la loro struttura a bande, fondamentali per comprendere appieno le proprietà dei cristalli fotonici bidimensionali (Cap. 2). Nel Cap. 3 sono approfondite le proprietà di propagazione della luce nelle guide d'onda realizzate in cristalli bidimensionali, in particolare la loro tipica relazione di dispersione e il regime di propagazione noto come regime di Luce Lenta (Slow Light regime). Nello stesso capitolo, si introduce, inoltre, un modello teorico per il Four-Wave Mixing, fenomeno non lineare solo recentemente osservato in questo tipo di guide. Il Cap. 4 introduce brevemente i processi di fabbricazione per questi dispositivi; vengono quindi discussi i punti critici di tali processi, modellizzati come disordine estrinseco, e l'impatto che questi hanno sulle proprietà di propagazione della guida. Gli ultimi due capitoli sono relativi alla parte sperimentale di questo lavoro. Sono state infatti studiate due tecniche per la caratterizzazione delle guide d'onda a cristallo fotonico. La prima è la mappa di riflettanza tempo-lunghezza d'onda (Cap. 5), sviluppato presso Thales Research and Technology (Paris, France), che permette di valutare le proprietà di propagazione della guida in funzione della lunghezza d'onda e l'impatto della dispersione indotta dal disordine estrinseco della guida. La seconda è la tecnica Heterodyne Pump-Probe, utilizzato presso il Dipartimento DTU Fotonik, Copenhagen, in una serie di esperimenti atti a indagare il regime di luce lenta e i ritardi ottenibili in tale regime.

Abstract:
Cette thèse étudie l’optique quantique multimode, aussi bien du point de vue de la génération que celui de la détection. Elle s’articule autour de trois volets. Nous étudions la génération de lumière comprimée multimode dans une cavité. Pour cela nous considérons la forme la plus générale de hamiltonien quadratique, permettant entre autres de décrire l’utilisation de plusieurs pompes dans un matériau effectuant du mélange à quatre ondes. Une approche combinant fonctions de Green et décompositions de matrices symplectiques est décrite. Cette théorie générique est appliquée à des cas particuliers. Dans un premier temps, des exemples en basse dimension sont donnés. Ensuite, une configuration d’oscillateur paramétrique optique pompé de manière synchrone (SPOPO) est décrite et étudiée ; les résultats obtenus montrent que ce système a un comportement très différent de celui du SPOPO utilisant une non-linéarité d’ordre 2. Ces travaux ouvrent la voie à la réalisation de peignes de fréquences quantiques avec des micro-résonateurs en anneau gravés sur silicium. Un autre problème examiné est celui de prendre en compte l’information temporelle obtenue lors du clic d’un détecteur de photon unique. Pour cela nous utilisons un formalisme multimodal temporel afin d’expliciter les opérateurs décrivant la mesure. Les principaux défauts des détecteurs réels, dont la gigue temporelle, l’efficacité finie et les coups d’obscurité sont pris en compte. L’utilisation des opérateurs est illustrée par la description d’expériences usuelles de l’optique quantique. Enfin, on montre que la lecture du temps de clic du détecteur permet d’améliorer la qualité de l’état généré par une source de photons annoncés. En troisième partie nous présentons un schéma de génération d’intrication hybride entre variables continues et discrètes, pour laquelle la partie discrète est encodée temporellement. Ce schéma est analysé en détail vis-à-vis de sa résistance aux imperfections expérimentales
This thesis studies multimode quantum optics, from generation to detection of light. It focuses on three main parts. Multimode squeezed states generation within cavity is studied. More specifically, we take into account general quadratic Hamiltonian, which allows describing experiments involving arbitrary number of modes and pumps within a medium performing four-wave mixing. We describe a generic approach combining Green functions and symplectic matrix decomposition. This general theory is illustrated on specific cases. First, low-dimensional examples are given. Then, a synchronously pumped optical parametric oscillator (SPOPO) is described and studied; it shows a very distinct behavior from that of the SPOPO using second order non-linearity. This work opens way to the realization of quantum frequency combs with ring micro-resonators engraved on silicon. Single-photon detectors are described taking into account temporal degrees of freedom. We give positive-valued measurement operators describing such detectors including realistic imperfections such as timing-jitter, finite efficiency and dark counts. Use of those operators is illustrated on common quantum optics experiments. Finally, we show how time-resolved measurement allows improving the quality of state generated by single-photon heralded source. In the third part we propose a protocol for generating a hybrid state entangling continuous and discrete variables parts, for which the discrete part is time-bin encoded. This scheme is aanalysed in detail with respect to its resilience to experimental imperfections

Abstract:
AbstractAttosecond four-wave mixing spectroscopy is a relatively new technique for studying ultrafast dynamics of highly excited states with exquisite temporal precision and spectral resolution. The attosecond four-wave mixing technique, as described in this paper, uses non-collinear beam geometries of one attosecond pulse together with two optical pulses to obtain background-free, spatially isolated emission signals in the extreme ultraviolet range that directly resolve coherent dynamics in the time domain. This method is advantageous by avoiding the strong spectral modulations that often complicate the interpretation of collinear attosecond transient absorption studies while also enabling greater control over the spatial and temporal characteristics of each light-matter interaction used to probe the ultrafast processes. This paper describes a broad range of attosecond four-wave mixing experiments performed in gas phase atoms and molecules, and a recent extension into solids.

It is noted that the former (whoopee) method does not depend on wave-vector matching within a macroscopic sample and can be applied to single-chromophore systems. A version of four-wave mixing using spectral interferometry is outlined. The ranges of interpulse delay within which each of several contributing wave-packet overlaps may take nonzero values are identified. Time-versus-time WPI interferograms for a model Hamiltonian are interpreted by using quasi-classical phase-space diagrams to identify conditions for non-negligible overlap between contributing multi-pulse nuclear wave packets. The effects of inhomogeneous broadening and optical dephasing are explored by including an additional, sluggish vibrational mode.

Abstract:
We study the process of four wave mixing in photonic time-crystals. We find that the phase matching condition is altered by the momentum band-structure of the time-crystal, enabling the enhancement of any chosen frequency.

Abstract:
Over the last few years, different types of instability associated with counterpropa- gating waves in a bulk Kerrlike medium have been discovered.1−3 Considering a finite response time for the nonlinearity, Silberberg and Bar-Joseph1 first predicted temporal oscillations and chaos at high intensity. Taking into account the extra degree of freedom due to the polarization state of the fields, Gaeta et al.2 have then shown that this polarization state is actually unstable above some intensity threshold. Finally, we have recently shown, using a linear stability analysis, that transverse instabilities also occur above another intensity threshold and an analytical expression has been given for this threshold.3 Here, we present a simple explicit analytical expression (in terms of the length of the medium and the tensor components of the susceptibility) for the polarization instability threshold in the case of equal beam intensities, considering only the first bifurcation. This instability can then be interpreted as a four-wave mixing self-oscillation. This result allows us to compare the different instability thresholds associated with contra- directional waves. It is shown that the transverse instability should dominate, not excluding however the possible onset of polarization instability at higher intensity.
