The PSW-002 is a solid-state polarization switch that can quickly and repeatably rotate the SOP of incoming light by a fixed angle, either 45 or 90 degrees.
The PSW-002 uses a magneto-optic rotator to switch the output polarization state between two output states separated by a relative angle of 45° or 90°. Both single mode and PM fiber pigtailed versions are available. With the PM option, the device functions as a TE to TM converter, switching the SOP between being aligned with the slow and fast axes of the PM fiber, or between the slow axis and 45 degrees from the slow axis. With the SM option, the device simply rotates the polarization ellipse either 45 or 90 degrees.
