Abstract

We present two types of optoelectronic time-domain packet switches, a photonic add-drop multiplexer, and a 4×4 packet switch, for high-speed asynchronous burst optical packets. They employ all-optical serial-to-parallel converters, optical single clock-pulse generators, and photonic parallel-to-serial converters that enable utilization of a compact highly functional complementary metal-oxide-semiconductor circuitry for label processing, packet switching, and buffering for contention resolution. We have experimentally confirmed basic operation of the packet switches for 40-Gb/s 16-bit asynchronous optical packets.
