Polarization Switch

Polarization Switch

All solid-state polarization switch can quickly and repeatablly rotate the incoming SOP via a fixed angle, either at 45 or 90 degrees. Both single mode and PM fiber pigtailed versions are available. With the PM option, the device functions as a TE to TM converter to switch the SOP between being aligned with the slow and the fast axes of the PM fiber, or between the slow axis and 45 degrees from the slow axis. With SM option, the device simply rotates the polarization eclipse either 45 or 90 degrees. The device can be used for PMD monitoring, polarization modulation, polarization detection, and polarization metrology.
