POLARIZATION
MANAGEMENT MODULES
General Photonics’ all solid-state polarization switch can quickly and repeatably rotate
the SOP of incoming light by a fixed angle, either 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, 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. The
device can be used for PMD monitoring, polarization modulation, polarization detection, and polarization
metrology.
