Abstract

Several results of investigations of leaky optical wave (LOW) excitation in LiNbO₃ planar waveguides at the nonaxial light propagation and of their acoustooptical interaction with surface acoustic waves (SAW) in such waveguides are presented. In experiments, leaky waves were excited by the total internal reflection of an ordinary polarized laser beam from the waveguide surface. The LOW excitation efficiency dependence and distortions of the reflected beam intensity distribution on the light propagation direction were investigated, the novel geometry of radiated ordinary mode conversion into the extraordinary one due to the diffraction of leaky waves on SAW was observed, and LiNbO₃ acoustooptical modulators using LOW were realized. Effects of holographic grating photorefractive recording in LiNbO₃ waveguides also were studied.
