Paper Abstract

In this paper a theoretical treatment on guided-wave acousto-optic (AO) Bragg interactions on a spherical waveguide together with new experimental results at significantly higher surface acoustic wave center frequency (500 MHz) using a LiNbO hemisphere block is reported. The theoretical analysis for the optical and the acoustic waves are carried out using the lowest-order asymptotic expansions and the resulting AO Bragg diffraction calculated using Green's function technique. Bragg diffraction experiments using LiNbO3 hemisphere block (3.1 cm Dia) at the optical wavelength of 0.6328 (mu) and the center SAW frequency of 500 MHz involve the physical dimensions that satisfy the assumptions required in the theoretical treatment. Efficient diffraction efficiency and large bandwidth as well as high quality focused spots of both the undiffracted and the Bragg-diffracted light beams obtained suggest potential use of the spherical surface for realization of integrated AO device modules.
