【Abstract】 According to the magneto-optic coupled-mode equations for the case of arbitrarily inclined magnetization, the noncollinear interaction between guided optical waves and three kinds of magnetostatic modes, namely, magnetostatic forward volume wave, magnetostatic backward volume wave and magnetostatic surface wave in the conventionally magnetized YIG film waveguides is analyzed. The diffraction efficiencies are expressed in terms of the complex envelope of Magneto Static Waves (MSWs). The theoretical results obtained are consistent with the experimental data. The conclusions obtained in the paper can be applied to the optimization of the MSW-based Bragg cells with applications to optical signal processing.更多还原
