Abstract: In this paper, the coupling optical mode amplitude equations under the perturbation of magnetostatic wave (MSW) have been derived with a new perturbation method; the Bragg diffraction efficiencies and the scanning characteristics of MSW-optical wave interactions are discussed; the nonoollinear interaction between magnetostatic forward volume wave (MSFVW) and the optical wave end-butt coupled into the YIG film is realized; and the effects of MSFVW frequencies and power on the interaction are studied.

Key words: magnetostatic forward volume wave, guided optical wave, perturbation, Intel-action
