摘要
提出了一种新的两段型高性能与偏振无关光隔离器的结构，给出了其设计思想和工作原理。对法拉第旋光器用的圆筒形磁铁进行了理论分析和计算，所得的结果对法拉第旋光器用的磁铁设计有具体的指导作用。通过借助矩阵光学理论，对光隔离器进行了数学分析，为与偏振无关光隔离器的性能分析和讨论作了有益的尝试。
A novel two-stage structure of polarization-independent optical isolator is presented, and its design idea and operating principle is also discussed. The cylinder magnet for Faraday rotator is analyzed and calculated theoretically, which results can give concrete instructions for the design of optical isolator. On the base of thoroughly studying the principle and structure of the optical isolator and utilizing the matrix optics,the properities of optical isolator are analyzed in mathematically,and it makes valuable try for more detail property-discussion.
