Accurate spectral characterization of polarization dependent loss

Abstract
Building on previous work, a rapid, automated, non-mechanical measurement system for spectral characterization of polarization dependent loss is presented. A deterministic fixed-states method in conjunction with real-time calibrated spectral information is used to infer wavelength-dependent Mueller matrix elements from power ratios at specific polarization states. Voltage-modulated liquid-crystal variable retarders set the input polarization states. A narrow, voltage-tuned filter generates a wavelength sweep from a broadband source. The sweep is calibrated in real-time by hydrogen cyanide reference lines. Actively balanced photodetection is employed to achieve low noise signals. I present polarization-dependent loss measurements from 0.0003 to 0.30 dB at 1550 nm to verify performance and also present results from artifact calibration standards of an all-fiber design.Proceedings Title
