This paper gives the results of calculations of the accoustooptic effect in
a. planar graded index wa.veguide obtained from the diifusjon of tita.nium to
a. Y-cut LiNb03. The effect of TE and TM modes are considered_ The effectiveness
of diHraction (TEm-TEm. TMm-TMm) and conversion (TEm-TEn, TMm
_T Mn. TEm _T Mm) of modes, depending on the acoustic power. is investigated.
Calcu1ations are carried out for acoustic wave of 360 MHz frequency.
