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 fabricate and experimentally demonstrate all-optical flip-flop switching based on novel Mach-Zehnder interferometer bistable laser structure. The MZI-BLD successfully acts as set-reset flip-flop with continuous light injection.
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.
We demonstrate polarization-insensitive all-optical flip-flop based on multimode-interference bistable laser diode. Dynamic switching is observed without waveform distortion even when the input polarization state is scrambled.
Cross gain modulation between two different optical signals, inserted through separate ports to an active MMI, has been experimentally measured. The observed trend of modulation reduction by increase of modulated signal power matches previous simulation results. An associated XPM is expected and could be optimized to enable using the active MMI in all-optical switching.
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.
Multimode interference bistable laser diode all-optical flip-flop has been considered to be a clever candidate to achieve all-optical memory devices. In this paper, basic results of polarization-insensitive operation of all-optical flip-flop are reported. Polarization-insensitive operation of static flip-flop was demonstrated with injection power level higher than +3 dBm.
An integrated semiconductor 1times5 InP-InGaAsP optical phased-array switch is fabricated and characterized. Using the carrier-induced refractive index change of InGaAsP waveguide, we achieve successful switching to five output ports with less than 60-mA current injection. Wide operating bandwidth covering the entire C-band (1520-1580 nm) and nanoseconds dynamic response are demonstrated, making it...
An integrated semiconductor 1times5 optical phased-array switch is designed and demonstrated for the first time. Using the carrier-induced refractive index change in the InGaAsP bulk layer, we achieve successful switching to five output ports with less than 60-mA current injection.
An MMI bistable laser diode optical flip-flop has been developed for all-optical packet switching networks. All-optical switching of 320 Gb/s packets has been successfully demonstrated by an optical label memory based on the optical flip-flop.
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.
