Abstract

We demonstrate an optical-signal-to-noise-ratio (OSNR) monitoring scheme of 200-Gbit/s PM-16QAM and 100-Gbit/s QPSK signals using Mach-Zehnder delay-line-interferometer with <;0.5 dB error for signals with up to 22 dB actual OSNR. We have also shown usability of this scheme by varying different parameters and have determined design guidelines to achieve a desired level of accuracy.
