EEOptics Corporation

High Speed Polarization Controller/Scrambler

EEOptics Corporation provides High Speed Polarization Controllers that convert any input polarization state to any desired output polarization state by externally applied driving voltage. EEOptics' high speed polarization controllers are developed based on its innovative the EEO crystals technology. They are fast with less than 10µs response speed, linear response to the control signal, long lifetime without limitation on the cycles, solid state without moving parts, completely vibration free, and compact in size.

Combining with the algorithm and the driver, EEOptics' polarization control module can work as a polarization scrambler.

EEOpcis offers high speed polarization controllers at multiple wavelengths:

  • 1550nm EEO high speed polarization Controller
  • 1310nm EEO high speed polarization Controller
  • 1064nm EEO high speed polarization Controller

Single-stage polarization rotators are also available.


  • Fast Response Speed (<10μs)
  • Linear Response
  • Long Life Time
  • Low Loss
  • Flexible Configuration
  • Compact in Size
  • Wide Response Bandwidth (DC~MHz)


  • Polarization Management
  • Polarization Scrambler
  • Polarization mode dispersion compensation
  • Polarization multiplexing
  • Polarization generator
