Optical Polarization Control

FPGA-driven polarization tracker based on an integrated-optic lithium niobate waveguide controller for fast, endless SOP tracking.

Compact high-speed polarization state generator module that switches between six distinct polarization states in a typical 45 µs.

Miniature all-fiber multimode scrambler OEM module that randomizes multimode fiber speckle patterns at 725 kHz for uniform, stable output light.

C-band all-fiber polarization scrambler module that randomizes output polarization to reach an output DOP below 5% averaged over 2 ms.

All-fiber polarization scrambler module that gives output DOP below 5% with multiple wavelength bands and remote control.

Reset-free polarization tracker module that holds a stable output SOP against input fluctuations, with internal or external feedback.

Solid-state magneto-optic polarization switch that rotates the SOP of incoming light by a fixed 45° or 90° angle in about 100 µs.

Compact magneto-optic module that generates 6 states of polarization (−45°, 0°, 45°, 90°, RHC and LHC) under 6-bit TTL control.

Miniature polarization scrambler module that generates discrete random polarization states at a user-selectable rate of 0.01 to 20,000 points/s.

All-fiber multimode scrambler that randomizes laser speckle patterns at 150 kHz for uniform time-averaged core illumination.
