层状YIG薄膜波导中的静磁正向体波与光相互作用

INTERACTION BETWEEN MAGNETOSTATIC FORWARD VOLUME WAVE AND OPTICAL WAVE GUIDED IN LAYERED YIG FILM

利用新的微扰方法导出了层状YIG薄膜波导中静磁波微扰下的光模式耦合振幅方程;讨论了静磁波-光相互作用Bragg衍射效率和扫描特性;实现了端面耦合方式下的静磁正向体波-光的非共线相互作用,并研究了静磁正向体波频率和功率对其的影响.

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.
