2×2全光纤声光开关的实验研究

摘要: 对基于光纤零耦合器的声光开关进行了实验研究,制作了零耦合器,并在此基础上设计和实现了工作波长为1550nm、损耗为0.2dB、耦合效率为98%、驱动功率为13.8mW的光纤声光开关.结果表明,此类器件可在光纤通信及光纤传感中得到应用.

Abstract: The acousto-optic switch based on optical-fiber fused null coupler is studied experimentally,a null coupler is fabricated,and a fiber acousto-optic switch with insertion loss,less than 0.2dB at 1550nm and coupled efficiency of 98% is realized.Because of its advantages,it is applicable in fiber telecommunication and detection.
