Full textThis thesis studies the influence of the fabrication parameters pf a Ti: LiNbO₃ electro-optic directional coupler on its figures of merits. A theoretical model has been developed and its predictions applied to the design of high-speed modulators for 1. 5 μm fiber-optic communication system. The optical properties of the guiding structure (mode size, coupling length) as a function of diffusion conditions are presented in normalized form. The results are then used to determine the fabrication parameters so as to minimize total insertion loss of a fiber pigtailed device. The electrode geometry is dictated by band with considerations ant the variation of the associated switching voltage is calculated as a function of diffusion parameters. Experimental results have been found to be in good agreement with the theoretical predictions. Suggestions to improve the figures of merit are put forward

Full textTo be in line with the standard of operational amplifier (opamp), designer integrates in his circuit several functionalities like a Rail to rail input and output, class AB output stage and low power consumption. For standard products, there is no outstanding performance but the average of all of them has to be good. In order to increase the number of functions on an integrated circuit, the power supply and current consumption are permanently decreasing. The aim of the designed circuits is to double the figure of merit (FOM) of the actual ST portfolio products. The FOM allows the comparison of similar opamps. It is defined by the ratio of the product of capacitive load x gain-bandwith product over the power consumption. The opamps’ state of the art has led this study to three stages analog cells. A DC gain higher than hundreds of decibel is required to use opamps in feedback configuration. As each stage of the structure introduces a high impedance node and as each high impedance node introduces a pole, the study of frequency compensation technics became essential for well optimized structures. To simplify the study of the opamps, three tools have been developed to help in the design of the frequency compensation network and to automate some tasks. This work has been followed by the realization of six cells. Three of them were designed to validate frequency compensation structure and the other three to satisfy a standard opamp datasheet. Nested Miller, Reversed Nested Miller and Multipath Nested Miller compensations were used in these circuits

Full textLT2C laboratory uses since recent years a low temperature sol-gel process to develop a magneto-optical composite material that is perfectly compatible with glass integrated optics. However, due to an actual low figure of merit, this material cannot be embedded on integrated non-reciprocal devices. In order to exalt the magneto-optical effects and figure of merit, the LT2C laboratory adopted a process based on opals to 3D structure the material. The selected process consists in elaborating direct opals by self-assembling monodisperse polystyrene microspheres on glass substrate. Those opals are then impregnated with a homogeneous solution of sol-gel silica precursors doped with cobalt ferrite nanoparticles. Resulting samples are later oven dried for 1 hour at 90°C. Finally, polystyrene spheres are dissolved in ethyl acetate to obtain a 3D structure formed by air voids in doped silica matrix. In this context, the objective of this thesis is to optimize the fabrication process of opals in order to improve their structural and magneto-optical quality. Furthermore, it consists in making a systematic study of the magneto-optical effect in these structures in order to investigate the spectral behavior of the Faraday effect and thus quantify the figure of merit. Analysis of SEM images and optical characterization prove that our elaboration process leads to the fabrication of opals with good structural and optical quality. Measurements of Faraday rotation and ellipticity as a function of applied magnetic field show hysteresis loops with an unambiguous non-reciprocal behavior. These observations highlight the magneto-photonic character of the doped inverse opals. A systematic spectral study of the magneto-optical effect in these 3D structures displays two peaks and an attenuation of Faraday rotation and ellipticity, respectively at the edges and the center of the photonic band gap. However, these significant spectral modifications do not increase the value of figure of merit. This ascertainment is primarily due to structural defects that lower the transmission magnitude of the doped inverse opals in comparison to a magneto-optical reference monolayer
