All-optical simultaneous 160-Gbit/s data selector and Fredkin gate using twin four-wave mixing processes in Si-nc slot waveguides

摘要

We design a Silicon nano-crystal (Si-nc) slot waveguide enabling tight light confinement and enhanced nonlinearity. By exploiting twin FWM processes in Si-nc slot waveguides, we simulate and implement simultaneous 160-Gbit/s data selector and Fredkin gate. Extinction ratio, Q-factor and eye opening are evaluated.
