Abstract :
Evanescent-coupling-induced group velocity dispersion (GVD) in a subwavelength silicon directional coupler is observed to significantly modify four-wave-mixing (FWM) spectra. As the separation between two silicon wires decreases, the increasing dispersion gradually suppresses the FWM gain.
