Product information "PSW-002 Polarization Switch"

1310, 1550 nm; IL <0.5 dB; Switching Speed 100 µs; Polarization Rotation 45°, 90°; ER >18 dB; RL >55 dB

General Photonics’ PSW-002 is a solid-state polarization switch that can quickly and repeatably rotate the state of polarization (SOP) of incoming light by a fixed angle, either 45° or 90°. Both single mode (SM) and polarization maintaining (PM) fiber pigtailed versions are available.

With the PM option, the PSW-002 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° from the slow axis. With the SM option, the device simply rotates the polarization ellipse either 45° or 90°.

The device can be used for polarization sensitive OCT, polarization sensitive OTDR or OFDR, PMD monitoring, polarization modulation, polarization detection, and polarization metrology. An optional driver board simplifies switch control by allowing the user to control the output SOP using TTL levels.
