Microstructuration par échange protonique sur niobate de lithium : application à la réalisation de fonctions de filtrage by Georges Bou Abboud( )

1 edition published in 2008 in French and held by 1 WorldCat member library worldwide

This work is dedicated to the study and the realization of distributed partially proton-exchanged Ti:LiNbO3 waveguides. The implemented technology allows the inscription of periodic and aperiodic structures, through a mask reproducing any pattern. The application is dedicated to the realization of tunable wavelength filters. Is is then possible to control the transmission function parameters and furthermore, allows the realization of structures presenting a predefined transfer function. The proposed analytical approach allows calculating the propagation constants for an optical waveguide, presenting any refractive index profile. Two methods are presented. In the first one, we consider that the effective index is constant according to the propagation direction in each of the microstructuration zones, while in the second one, which is more realistic, we take into account the fact that the effective index in each of the exchanged zones varies according to this direction. The approaches which were developed allowed notably establishing the limits of this technology
