La première démonstration mondiale du potentiel de l’optique adaptative pour l’astronomie a été effectuée en 1989. Ces travaux ont démontré qu’il était possible de compenser les effets de la turbulence atmosphérique et d’atteindre la

Integrated optics, applied to astronomical interferometry, bring several decisive benefits compared to bulk optics : mechanical and thermal stability, small size, facility to realize combiners for many telescopes. At this time, numerous compoments we

Depuis la fin des annees 90, les astronomes utilisent l’interferometrie de maniere reguliere comme outil d’observation pour depasser la limite de resolution des plus grands telescopes actuels. Apres une periode de validation au moyen de premiers

In this paper we present new infrared waveguides based on proton-exchanged Lithium Niobate samples. Characterization of the waveguides in the visible and near infrared allows to develop a wavelength dependence function for refractive index and birefr
