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.
The all-optical response of a semiconductor ring laser to two optical injections demonstrates very digital hysteresis with externally controllable switching threshold, enabling the device to be used for all-optical pulse regeneration.
