WLS-Series WheeLED Multi-wavelength LED Light Sources

1280-1620 nm; SOP Sampling Rate ≤4 MHz; Analog Bandwidth 1 MHz; Input Power Dynamic Range 45 dB; IL ≤1.6 dB; PDL <0.25 dB; PMD <0.1 ps; RL 45, 55 dBLunas’ PSY-201 deterministic polarization synthesizer/analyzer generates and maintains any state of polarization (SOP), regardless of the input SOP. It combines General Photonics’ patented controller, polarimeter, and control algorithms into an instrument that functions as both an SOP generator and a polarization analyzer.The generated SOP and the corresponding Poincaré representation are displayed on a PC via USB interface. Output SOP can be defined by Stokes parameters, by manually tuning the SOP to any point on the Poincaré sphere or by optimizing a polarization-dependent metric. Once a desired output SOP is found, the instrument maintains the SOP against input SOP fluctuations.The user can generate 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.The PSY-201 polarization synthesizer/analyzer contains programmed SOP traces of common polarization variations. It can also function as a polarization scrambler, generating SOP scans with user-defined parameters and, with the internal polarization controller disabled, it can function as an in-line polarimeter, displaying the instantaneous SOP and DOP of the input light beam.Features include a data logging function for long-term measurement of polarization changes of up to 1 billion points, 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. PSY-201 puts all of the tools necessary for polarization management at your fingertips.Key Features:Sampling Rate: Up to 4M SOP (State of Polarization) Samples/sAnalog Bandwidth: 1 MHzInput Power Dynamic Range: 45 dBOperating Wavelength Range: 1480 to 1620 nm, 1280 to 1314 nmReal-time Poincaré Sphere DisplayHigh-speed SOP Generation and TrackingHigh-speed Analog Output of SOP & DOP (Degree of Polarization)Data Logging of SOP Changes up to 1 Billion PointsMaximum Insertion Loss (IL): 1.6 dBReturn Loss: 45, 55 dBPolarization Dependent Loss (PDL): <0.25 dB Polarization Mode Dispersion (PMD): <0.1 psOperating Power Range: -35 to +10 dBmApplications: Polarization Sensitivity Analysis of Receivers; Monitoring of System SOP/DOP; PER Measurement; Polarization Generation and Stabilization; Sensor System Characterization; 100G System Characterization
