INTERACTION ACOUSTO-OPTIQUE EN OPTIQUE INTEGREE SUR VERRE ET APPLICATIONS

Abstract : The ions exchange technology developed and controlled at IMEP some years ago, has allowed the realisation of a lot of optical functions for telecommunications, for astrophysics and for physical, chemical and biological quantities measurements. Today research is oriented to doped glass and hybridisation for active components realisation. Adding non linear functions gives new prospects to this technology. An example of non-linearity is a mechanical constraint applied on a waveguide. This constraint will change the refraction index of the guide. An acoustic wave which propagates inside or over the glass will change locally its refraction index. This thesis is dedicated to acousto-optics interaction on glass. Two types of acoustic waves are studied, bulk waves and surface waves. The result of this research enabled us to simplify an displacement sensor developed before within the laboratory and to design a new polarisation analyser integrated on glass. The prospects of this work are to introduce the acousto-optics effect in glass integrated optics, to exploit it and to improve it for the realisation of new optical functions.
