Novel all-optical implementations for logic AND and XOR gates are experimentally demonstrated at 2.5 Gbit/s based on cavity-enhanced four-wave-mixing (CE-FWM) combined with optical injection locking phenomena in monolithically integrated semiconductor ring lasers (SRLs). An all-optical AND gate with simultaneous wavelength conversion has been achieved using CE-FWM. An XOR function is demonstrated...
Reconfigurable all-optical multicast at multi-gigabit data rates has been realised using simultaneous multi-wavelength conversion based on cavity-enhanced four-wave-mixing in a monolithically integrated semiconductor ring laser. The scheme provides high efficiency, low power penalty, and cost-effectiveness.
