Abstract :
A high sensitivity in-band OSNR monitor system integrated on SOI platform is presented. The device exploits a narrow-band microring resonator to select the portion of the channel spectrum that is most sensitive to OSNR variations, and performs an autocorrelation measurement using a Mach-Zehnder interferometer. The proposed scheme allows in-line OSNR monitoring from 8 dB to 28 dB, with 0.2 dB accuracy.
