BIG磁光隔离器的研制

BIG MAGNETO--OPTICAL ISOLATOR

用非稀土磁光石榴石晶体，金女铁硼永久磁铁和格兰一汤姆逊棱镜研制的磁光隔离器．实验结果在１．５２μｍ波段正向插入损耗＜０．６ｄＢ，反向隔离度＞３６ｄＢ．

The magneto-optical isolator,which is made of nonre-earth magneto-optical garnetcrystal, Nd_2Fe￣(14)B Permanent magnet and Hrant--Thomson prism, is reported in the paper. The experimen-tal results we positive directional insertion loss<0.6 dB and negative directional isolation ratio>36 dB.
