| Abstract: | An analysis of the dependence of the Bragg acoustooptical interaction efficiency of TE modes in a graded-index optical waveguide
on the acoustic surface wave (ASW) frequency has been made. It is shown that two waveguides having different optical parameters
but the same number of modes are described practically by the same frequency dependence. This conclusion is confirmed by the
calculation for two four-mode waveguides on the Y-cut lithium niobate. The frequency dependence for various processes in the
range 50÷550 MHz has been experimentally measured. |
