Texte intégralIn the field of neuroscience, the advent of light-sensitive optogenetic tools has opened new opportunities for precisely controlling neuronal activity and study brain functioning optically. In optics, this has motivated the development of various light-delivery and collection strategies to functionally image and manipulate neural activity with high spatiotemporal precision. Particularly, light-shaping approaches, such as Computer-Generated Holography combined with Temporal Focusing, have enabled temporally precise targeting of individual neurons or clusters with near single-cell accuracy within volumetric spaces of hundreds of microns. This precision is crucial to get critical insights into the neural code and establishing connections between neural activity with behavior and perception at fine scale. Despite these advancements, challenges persist in enabling complex brain investigations, especially when it comes to control vast populations of cells with high spatiotemporal precision in depth. During my thesis, I particularly focused on those challenges and developed new light-shaping optical strategies aiming at (i) expanding the number of excitable neurons, (ii) improving temporal resolution and (iii) increasing the penetration depth of cell-targeted multiphoton optogenetic investigation based on phase-modulation light-targeting.Initially, I concentrated on developing an ultra-fast two-photon (2P) optical system (FLiT), where a multiplexing LC-SLM and a galvanometric mirror are coupled to allow kHz-rate switching of spatially precise illumination patterns on the sample. This serves two primary purposes. Firstly, it enables to optically tune the relative spiking time of distinct cells with a temporal resolution of about one order of magnitude higher compared to previous methods. Secondly, FLiT allows targeting a given ensemble of cells by reducing the excitation power budget by a 4-5 factor, while minimizing light-induced thermal rise. To push forward this approach, I further modified the original optical design by including a de-scan unit (deFLiT) which enabled to enlarge the number of usable holograms and increase even further the power gain and temporal precision of conventional FLiT .In the second phase of the thesis, I focused on a three-photon (3P) holographic system to conduct optogenetics experiments deeper inside the brain. I designed and built the system and I then validated it by photo-activating various opsins and driving high-rate firing in targeted neurons under a verified 3PE regime. Compared to previous holographic 2P-photon systems, this approach will enable the extension of all-optical investigations to deeper brain regions.These new strategies will be important for studying neuronal circuits with rapid and precise optogenetic stimulation across large neuronal ensembles in depth

Texte intégralIn this PhD thesis we study 2nd and 3rd order optical non-linearities in optical nanofibers, which are obtained by stretching standard fibers until their diameter becomes of the order of magnitude of the wavelength. The first application is the realization of wavelength converters in the visible range in the sub-ns regime, range which is only minimally covered by pulsed sources. The principle of these converters is to use stimulated Raman scattering in the evanescent field immersed in a liquid. By defining and optimizing their operating range, we have reach external conversion efficiencies from the pump at 532 nm to the first Stokes order of ethanol at 630 nm near to 60%. The performances of our converters are very repeatable and open the way to a new family of very compact, reliable and all-fibered components.The second application is the study of a source of correlated photon pairs for quantum telecommunications. Our source is based of parametric fluorescence on the surface of a silica nanofiber. In the phase-matching we propose, the pump wave is emitted on the mode TM01 at 775 nm and the photon pairs are emitted around1.5 μm in the fundamental mode, enabling a recoupling with only a few losses in the optical network. Our study mainly concern the choice of the standard fiber enabling to optimize the efficiency of the mechanism, the conception of the nanofiber and its tapers as well as the implementation of preliminary experiments for the excitation of high ordrer modes

Texte intégralPhoton-pair sources are a basic block for implementation of quantum information and telecommunication. A microstructured fibered source with liquid core induce a Raman scattering noise reduction, and at the same time allows a simple and lossless coupling to telecom network, with an engineering of its emission properties through the structure and liquid choices. This work focus on four-wave mixing leading to photon pairs emission in such a source. As existing models lack a correct emph{quantitative} description of nonlinear phenomena for pairs emission, we propose here one based on the D field to do so. We show a mismatch between the spectrum form usually expected and the experimental one. To explain this, we develop a model describing the effects of guide nonuniformity, meaning variation of its propagation properties along itself. Through an initial and simple analytical approach, we demonstrate the spectrum spreading and the diminution of the maximum of emission pairs rate. With a piece-wise numerical description for real guides, we highlight the very strong sensitivity of the emission spectrum towards nonuniformity. Another effect arising from this feature is the spectrum differentiation depending on the propagation direction within the guide. Upon pairs polarization entanglement by inserting the guide into a Sagnac loop interferometer, such nonreciprocity induces a deterioration of pairs visibility. In order to counteract this effect, we propose, based on first encouraging results, a simple solution involving a symmetrization of fibers profile during their manufacture. This study paves the way for taking into account inherent nonuniformity of real waveguides, which strongly impacts their photon pair emission

Texte intégralThe goal of this work is the study in 3Jie of the rnechanisms involved in the absorption of photons in the (1232) resonance region. One, two, or three nucleons participate in this absorption depending upon the specific reaction induced : pion photo-production proceeds preferentially through absorption on a simple nucleon, whereas in photodisintegration without pion emission the photon is absorbed by few-nucleon subsystems. The experiments were performed at the Saclay Linear Accelerator with the quasi-mono-chromatic in flight positron annihilation photon beam. Pion and proton spectra were measured using magnetic spectrometers for several angles from 20° to 72°. Photon energies were in the 210 - 450 MeV range. For each kinematical setting a corresponding measurement of the reactions ll(ynl-)n and D(yp)n allowed the comparison of the helium-3 cross sections to these more elementary ones. Our experimental results are compared to theoretical calculations utilizing realistic He wave functions. Impulse approximation models which incorporate the nucleon fermi motion cannot reproduce the pion coherent photo-production 31le( yn+). The theoretical predictions of a charged pion quasi - free photo-production which take into account only partially the final state interactions overestimate the experimental cross sections. For 3ue photo-desintegration, without 1r production the calculations include short range correlations, mesonic exchange currents, and final state interactions. They agree reasonably well with the measured spectra in the region where absorption by a nucleon pair dominates, but they underestimate the cross section in the high momentum tip region. Inclusion of three body effects appears necessary in order to explain this experimental feature
