Semiconductor integrated photonic devices and circuits on InP for high-speed and large scale optical switching, optical buffer memories, and for digital photonic processing are reviewed, as well as PLC-based optical lead frames for multi-port coupling.
The static and dynamic characteristics of a monolithically integrated InP 1 ?? 16 optical phased-array switch are presented. The device demonstrates static switching with an average extinction ratio of 18.6 dB, on-chip loss below 7 dB, and wavelength dependence of less than 0.8 dB in the entire C-band. A 40-Gb/s nonreturn-to-zero signal is transmitted through the switch with a power penalty below...
Integrated InP/InGaAsP phased-array 1 times 16 optical switch is fabricated and characterized for broadband WDM optical packet switching. Wavelength-insensitive operation covering the C-band and penalty-free transmission of 40-Gbps signal are demonstrated.
A review is given on InP-based integrated optical devices for robust and efficient photonic networking. The devices include an all-optical flip-flop for digital processing and memory functions in the network, and a phased-array optical matrix switch for fast and scalable switching of optical burst/packets.
We experimentally demonstrate an all-optical flip-flop using a multimode interference bistable laser diode. It is based on bistable switching between two cross-coupled lasing modes. Pulse width conversion experiment and operation speed assessment are also presented.
