摘要: 光纤无源开关器件是近期光通信领域研究的热点.本文就应用于光纤开关的一种新型晶体材料进行理论分析和实验研究,确定该材料可应用于0.5～1.5 μm频域内各种光纤开关器件,其驱动脉冲电流低于4 A,脉冲宽度在5 μs左右.

Abstract: The research on passive fiber switch is attracting the people's attention in the optical communication. In this paper a new Magneto-optical crystal material used in the fiber switch has been researched theoretically and experimentally.It is decided that the fiber switch made of the material can work in the wavelength rang of 0.5～1.5μm, the excitation pulse current for the switch is lower than 4A and the pulse duration is about 5μs.
