DEP Depolarizer General Photonics Datasheet

Product information "DEP Depolarizer"

1310, 1550 nm; IL 1.0 dB; DOP <5%; ER <0.5 dB; RL 55 dB

General Photonics’ DEP depolarizer module is a passive device (requiring no external power) that depolarizes laser output. The standard configuration can be used for coherence lengths less than 10 m. Custom units can be specified for coherence lengths of multiple kilometers.

The DEP polarizer is ideal for minimizing the polarization sensitivity of fiber optic sensor systems such as systems for quasi-distributed temperature and strain sensing based on fiber Bragg gratings (FBG), systems for distributed temperature and strain sensing based on Brillouin or Raman scattering and systems for distributed acoustic sensing based on Rayleigh scattering. It can also help to eliminate the effects of PDL or polarization sensitivity of optical components and instruments. Equally important, it can be used for depolarizing pump lasers to eliminate the polarization sensitivity of Raman amplifiers.

The DEP polarizer is packaged in a small (85 × 60 × 10 mm), rugged aluminium box, providing high performance and superb environmental stability. The internal structure and package size may be different depending on the coherence length or spectral width of the light signal to be depolarized. Contact AMS Technologies for an optimized configuration for your intended applications.

PSY-201 Polarization Synthesizer/Analyzer

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
