摘　　要：结合Lyot型消偏器和Walk-off型光隔离器的原理与结构,提出一种具有隔离功能的消偏器。从理论上对其插入损耗和隔离度进行性能分析,通过实验测试其偏振度与隔离度,分析与实验结果表明:该器件结构紧凑,即可对入射光消偏,又能隔离反向光。Based on a research into the principles and structures of Lyot depolarizer and Walk-off isolator,a polarization-dependent depolarizer with isolation function is proposed.The insertion loss and the isolation of this novel device are analyzed theoretically,and its output degrees of the polarization and the isolation are obtained respectively in test experiments.Analysis and experiment results show that,this device with a more compact structure,can not only depolarize input light,but also prevent reflecting light.
