Reference number: GPC-POS-20x

PolaStay™ polarization stabilizers from General Photonics actively maintain a stable output state of polarization (SOP) against rapid input SOP fluctuations, compensating for an input polarization discontinuity in as fast as 5 ms, or tracking without resets against a continuous input SOP rotation of up to 32π/s.

Description

Reset-Free Polarization Stabilizer - PolaStay™

This unique family of products combine General Photonics’ polarization controller, in-line polarization monitor, and proprietary algorithm to find and maintain the target SOP. The instrument’s output fiber can be either single mode fiber or PM fiber with the output polarization aligned to its slow axis. When a polarizer is placed at the output, the maximum power fluctuation caused by input polarization fluctuation is less than 0.1 dB.

Features PolaStay:

  • Reset free operation
  • 5 ms recovery time
  • 32π/s tracking speed
  • Front panel control parameter setup
  • Low insertion loss

Applications PolaStay:

  • Optical amplifier polarization stabilization
  • Polarization demultiplexing
  • Elimination of polarization fading
  • Coherent communication
