Ultra-Fast Polarization Scrambler

0.3~5MHz, Bidirectional
  • No Moving Parts
  • High Reliability
  • Solid-State High Speed
  • Compact Size
  • Low Power Consumption



The polarization scramblers are based on fast speed electro-optical materials functioning as phase retardation with three plates oriented at 0, 45 and 90 degrees. They are modulated at three fixed frequencies with a built-in driver that only requires a DC power input. It converts any input state of polarization to randomly polarized states covering the Poincare sphere. The polarization scrambler is designed to meet the most demanding operational requirements of ultra-high reliability, fast response, wavelength insensitive, compact size to provide an ultimate solution for polarization randomization.
