Reset-Free Polarisation Stabiliser - PolaStay™

The PolaStay™ polarisation stabiliser actively maintains a stable output state of polarisation (SOP) against rapid input SOP fluctuations, compensating for an input polarisation discontinuity in as fast as 5 ms, or tracking without resets against a continuous input SOP rotation of up to 32π/s. This unique product is a complete system consisting of General Photonics’ polarisation controller, in-line polarisation monitor, and proprietary algorithm.
