The on-chip integration of all-optical random-access memories based on a photonic crystal nanocavity was achieved. Their ultralow power consumption, small footprint, and 40-Gb/s optical signal capability might be beneficial for future optical packet processing.
We demonstrate 1times5 broadband WDM optical packet routing with monolithically integrated phased-array switch on InP. Using a synchronized eight-port current driver, error-free forwarding of 8 times 40-Gbps multi-colored packet is achieved with Lt25-mA current injection.
A monolithically integrated 1times5 InP/InGaAsP optical switch based on optical phased array is fabricated and characterized. Wide operating bandwidth covering entire C-band (1520-1580 nm) and nanoseconds dynamic response are demonstrated for the first time.
We have demonstrated all-optical packet switching, in which an MMI-BLD optical flip-flop worked as a label memory. The optical flip-flop allowed self-routing of multiple-wavelength packets with 338-ps switching time and 14-dB on-off ratio.
