In-band OSNR monitor for DP-QPSK signal with high-speed integrated Stokes polarimeter

We propose an in-band OSNR monitor based on high-speed polarization analysis. We fabricated a high-speed integrated Stokes polarimeter with a PLC-based polarization filter, high-speed photodiodes and trans-impedance amplifiers, and carried out proof-of-concept experiments with 100-Gb/s DP-QPSK signals.
