Applications of the Acousto-Optic Effect on Glass Integrated Optic Devices

We present in this paper a study of acousto-optic interactions with guided waves on glass substrate. A beam of elastic of waves in the Megahertz range, generated with a PZT ceramic, crosses a waveguide realised by ion-exchange in a glass substrate. Elastic waves modify locally the refractive index of glass. We make use of this effect to propose novel integrated sensors like a polarization analyzer sensor and to improve devices like optical modulators and displacement sensors.
