Dual-microring resonator-coupled cross-connect switch element for on-chip optical interconnection

We demonstrate dual-microring resonator-coupled cross-connect switch element integrated with a lateral p-i-n diode on a silicon-on-insulator substrate. We realize 10-Gbit/s data routing/switching in silicon waveguide crossings by using carrier-dispersion effect with ∼0.7/0.85ns switch-on/off times.
