We report optical performance monitoring via slow-light enhanced third harmonic generation in a 2D silicon photonic crystal waveguide. We achieve all-optical in-band OSNR monitoring of a 40Gb/s Return-to-Zero signal with significantly better performance than methods based on quadratic response functions.
