We demonstrate excellent all-optical demultiplexing of 40-Gb/s base-rate channels out of 160- and 320-Gb/s single polarization optical time-division-multiplexed data streams. The demultiplexer utilizes a semiconductor optical amplifier and an optical filter placed at the amplifier output. The center wavelength of the filter is blue-shifted from the wavelength of the clock signal, so that ultrafast chirp dynamics can be employed for optical switching. Error-free demultiplexing was achieved at very low optical switch powers: 3.5mW(160-Gb/s data), 6.3mW(320-Gb/s data), and 0.09 mW (40-GHz clock). The proposed demultiplexer has a simple structure and allows monolithic integration.read more

All optical batcher banyan switch, batcher switch, banyan switch and contention manager
TL;DR: In this paper, the contention manager detects and resolves routing contentions between incoming optical signals prior to outputting the signals to the Banyan switch, and uses a photonic comparator in contention manager to detect contention.

All-optical packet-switched interconnection network based on modular photonic digital processing
TL;DR: The authors present two modular architectures, based on the crossbar and the Batcher-Banyan topologies, capable of forwarding fixed-length packets with two classes of service, which use photonic digital-processing subsystems built by combining a single integrable module which exploits cross gain modulation in a semiconductor optical amplifier.
