Abstract

A compensation scheme for thermally induced birefringence in Faraday isolators is proposed. With the use of this scheme a 36-fold increase of the isolation degree was attained in experiment. A comparative analysis of the considered scheme and the earlier Faraday isolator schemes with high average radiation power is performed. A method for optimizing the earlier Faraday isolator scheme with birefringence compensation is developed.

摘要

提出了一种用于法拉第隔离器中热致双折射的补偿方案。通过使用该方案，在实验中实现了隔离度提高36倍。对所考虑的方案与早期具有高平均辐射功率的法拉第隔离器方案进行了对比分析。开发了一种用于优化具有双折射补偿的早期法拉第隔离器方案的方法。
