Full textThe work presented in this thesis carries on the development of a new type of polarizing element of the emission of a laser by means of a diffraction grating integrated monolithically to one of the multilayer mirrors of the laser. Two types of laser and polarizing element were studied : - Polarization of the emitted beam of a monolithic microchip Nd : YAG cavity by means of resonant diffraction grating engraved in the last high index layer of the output mirror and, - Generation of a radially polarized beam in a high power Nd : YAG lasers by means of concentric diffraction grating integrated to the rear mirror of the cavity. The different polarizing principles of these mirrors as well as fabrication and characterization methods are described. Demonstrators have been achieved and have been tested in laser cavity

Full textChemokines and their receptors compose an important communication System, controlling lymphocyte navigation throughout development, homeostasis, and inflammation. Here we show that immature dendritic cells use this versatile communicational System to deliver tonic signals to T lymphocytes in the absence of antigen. Chemokinetic effects support multiple sequential interactions with dendritic cells, with repetitive contacts ultimately favouring the induction of early lymphocyte activation markers. Adhesive interactions involving the pair ICAM-l/LFA-1 are essential for effective signal flow at these antigen-independent interfaces and provide the physical support for lymphocyte scanning activity. Cellular locomotion is an intrinsically polarized process. Our data demonstrate that an evolutionary conserved polarity complex, consisting of Par6 and atypical PKC zeta, mediates T cell polarization downstream of chemokine receptors. We identified an essential requirement for PKC. Zeta in an early symmetry breaking step that settles the anterior-posterior axis of the cell. Once the polarity axis is established, PKC zeta drives uropod formation by a previously unrecognized pathway that involves functional inactivation of the myosin-binding protein Lgl2. Failure to transduce PKC zeta-dependent signals downstream of chemokine receptors renders the DC scanning process very inefficient. Altogether our findings suggest that effective accumulation of tonic signals in the steady state might critically depend on lymphocyte motor activity, which in turn is regulated by a signalling cascade that relays input from chemokine receptors to PKC zeta and Lg12

Full textThis work deals with linear and high efficiency microwave power amplification in GaN technology.The first chapter is dedicated to the general context of wireless telecommunication with a special emphasis on the RF power amplifier. The most representative figures of merit in terms of linearity and power efficiency are introduced.The second chapter deals more specifically with the GaN technology and GaN-based transistor for microwave power amplification. A description of the principal architectures found in the literature related to high efficiency and linear amplification is summarized.In the third chapter, the developed envelope time-domain test bench is presented. Time-synchronization and envelope calibration procedures are discussed. As an illustration, a new specific wideband NPR measurement is presented and experimentally validated.An innovative power amplifier architecture is presented in the fourth chapter. It is based on a specific dynamic gate biasing technique of the power amplifier biased close to the pinch-off point. A 10W GaN S-band demonstrator has been developed. Compared to fixed class-B conditions, a linearity improvement has been reported without any prohibitive efficiency degradation of the RF power amplifier. Finally, an investigation of the proposed technique for the efficiency improvement in the drain envelope tracking technique is proposed

Full textFor the past forty years, the growth of fiber telecommunications has led to the development of integrated optical components. However, due to technological issues, a device has not yet been realized: the optical isolator, which propagates light in a single direction. Our work fits into this context. It deals with the integration of an isolator using the Na+/Ag+ ion-exchange technology. The configuration we adopted consists of three elements on chip: a polarization splitter and two 45 ° polarization rotators, one is reciprocal and the other is not. The polarization splitter has been realized in the shape of an asymmetrical Y junction. After a theoretical study, we present the fabrication process and experimental results. State-of-the-art diaphonies of (31.1 ± 0.4) dB and (32.7 ± 0.4) dB have been measured in TE and TM mode over a bandwidth larger than 70 nm. The magneto-optical part of the study has been undertaken in collaboration with the Laboratoire Télécom Claude Chappe (LT2C) from Saint Etienne, France. The Faraday rotator is a selectively buried waveguide on which a magneto-optical material has been deposited using a sol-gel process. A non-reciprocal rotation of 50 ° has been measured, hence validating the hybrid approach. A novel fabrication process is presented for a reciprocal mode-evolution polarization rotator. The process consists in the burring of a waveguide under an electric field presenting a transverse inhomogeneity. We finally propose a fabrication method of the complete optical isolator. It is based on the monolithic integration of the three elements
