摘要
该文报道了一种具有偏振保持能力的光纤耦合声光器件,对声光介质及保偏光纤的偏振特性进行了分析,并对器件设计思路及性能参数进行了介绍。样品器件采用TeO2作为声光介质;PM980光纤作为耦合光纤;在工作波长1 053nm、频率100 MHz下获得插入损耗为2.4dB、通断消光比为50dB、偏振消光比为22.24dB。
This paper reported a fiber coupled acousto-optic device with polarization maintaining ability.The polarization characteristics of acousto-optic medium and polarization maintaining fiber were analyzed,and the design and performance parameters of the device were also introduced The experimental device using TeO2 as acousto-optic medium,PM980 fiber as coupling fiber.A result of insert loss 2.4dB,extinction ratio 50 dB and polarization extinction ratio 22.24 dB has been obtained at 1 053 nm operating wavelength and 100 MHz operating frequency.
