本开关型SOA, 又称为Switch或Shutter SOA, 蝶形封装, 保偏尾纤, C和L波段工作, 可实现1nS的开关式切换速度, 高达70dB的On/Off消光比, 使得它成为极为理想的超高速1×1式光开关. 另外, 可提供配套驱动电路.
Thorlabs’ BOA1004PXS polarization-dependent switch enables full control of the power level, making it ideal for high-power laser pulse generation systems such as cavity ring-down sensors and LIDAR systems. The device comes in an industry-standard, 14-pin butterfly package with PM fiber pigtails that are terminated with FC/APC connectors and key-aligned to the slow axis.
