摘要

分析了形成单模集成光隔离器的多层结构，重点讨论了该器件与相干通信系统中使用的单模光纤相匹配所需要满足的尺寸条件。磁光层位于有源层的正下方，以提高隔离器的性能。研究了多层波导中的基模行为。研究了具有法拉第结构的外磁场下波导中的模式传播，结果表明，基片的比法拉第旋转越高，器件的性能越好。

Single-mode isolator in integrated optics

A multilayer structure forming a single-mode integrated optical isolator is analyzed with special emphasis on the dimensional conditions to be fulfilled in order to match the device with single-mode optical fibers optically used in coherent communication systems. A magnetooptical layer is included just below the active one in order to improve the performance of the isolator. The fundamental mode behavior in the multilayer guide is investigated. The mode propagation in the guide in an external magnetic field with Faraday configuration is also studied, and it is shown that the performance of the device improves with higher specific Faraday rotation of the substrate.<>
