Polarization Synthesizer/Analyzer (PSY-201)

The PSY-201 is a deterministic polarization controller that can generate and maintain any state Specifications: Operating Wavelength Range 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. 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. Another attractive feature is that the user can generate any of 6 distinct SOPs (0°, 90°, ± 45°, RHC and LHC) for Mueller matrix calculations, or select any of the 6 states at the touch of a button. Furthermore, the instrument can generate several preprogrammed SOP traces that emulate certain common polarization variations. The instrument can also function as a polarization scrambler, generating SOP scans with user-defined pattern and speed. Finally, with the internal polarization controller disabled, PolaFlex™ can function as an in-line polarimeter, displaying the instantaneous SOP and DOP of the input light beam. Features include long-term SOP monitoring, SOP markers for angle measurement, and a "SOP replay" function in sphere display mode, as well as extended triggering capability in oscilloscope mode. It puts all of the tools necessary for polarization management at your fingertips.
