本文研究了铁磁钇铁石榴石薄膜的光波导模与微波激发的自旋波之间的相互作用。综述了各种物理效应，并讨论了它们的实际应用。将传统的微波-光波互作用方法推广到微波功率变高、磁性薄膜非线性起决定性作用的情况。沿着传统的器件如磁光布拉格盒、移频器、调制器，考虑了一类新的非线性器件，并给出了实用的建议。(C)1999 Elsevier Science B. V.保留所有权利。
The properties of ferrimagnetic yttrium-iron-garnet films are investigated with respect of mutual interactions between optical wave guided modes and spin waves excited by means of microwaves. Various physical effects are reviewed and their practical applications are discussed. Traditional methods of microwave-optic waves interaction are extended to the case where the microwave power becomes high and the nonlinearity of the magnetic film plays a crucial role. Along with traditional devices such as magneto-optic Bragg cells, frequency shifters, modulators a new class of nonlinear devices is considered and practical recommendations are given.
