摘　　要：根据微波静磁波(MSWs)和导波光(GOWs)的相互作用原理,给出了激发多个频率静磁波时衍射光的偏转角和光衍射效率的计算方法,并据此实现了利用静磁波频率和功率分别控制衍射光偏转角和衍射效率的目的。基于此原理设计的新型磁光开关可根据不同的组播需求同时对不同的输出端进行功率输出,弥补了传统光开关结构难以实现动态组播的不足。According to the theory of diffraction interactions between microwave magnetostatic waves （MSWs） and guided optical waves （GOWs）, the methods of calculating the deflection angles and diffraction efficiencies of the diffracted lights in the case of multifrequency MSWs were shown. The deflection angles and diffraction efficiencies can be respectively controlled by corresponding MSWs frequencies and powers. Based on this principal, a novel magnetooptic switch was designed which can export optical power to different ports simultaneously according to different multicast demands, making up the deficiency of the traditional optical switches which are difficult to realize dynamic multicast.
