PSM-002 Miniature Polarization Scrambler
The PSM-002 Miniature Polarization Scrambler is a small module that generates discrete, random states of polarization (SOP) at a user-controllable rate.
The PSM-002 uses a fiber squeezer polarization controller to generate discrete, random polarization states at a user-controllable rate between 0.01 and 20,000 points/s, distributed for uniform Poincaré sphere coverage. It can also perform triggered random state generation for synchronization with other equipment in the system. It is designed for integration into sensor and communication systems, and is available either as a standard board for lab applications or fully enclosed in a watertight enclosure for applications in high humidity environments. It also comes in either standard or extended temperature versions.
