  • Polarization Synthesizer/Analyzer - PolaFlex™

Reference number: GPC-PSY-201

The PSY-201 is a deterministic polarization controller that can generate and maintain any state of polarization (SOP), regardless of the input SOP. It combines General Photonics’ patented polarization controller, in-line polarimeter, and control algorithm into an instrument that functions as both a polarization state generator and a polarization analyzer.

Polarization Synthesizer/Analyzer - PolaFlex™

The generated SOP and the corresponding Poincaré Sphere representation can be displayed on a computer screen via USB interface. The output SOP can be specified by inputting Stokes parameters using the front panel keypad or by manually tuning the SOP to reach a specific point on the Poincaré sphere or to reach an optimum value of a polarization-dependent metric. Once a desired output SOP is found, the instrument can automatically maintain this SOP against input SOP fluctuations.
