Multiple recirculations through an optical buffer using a fast-recon-figurable AVC based Crosspoint switch matrix is shown. A 10 Gbit=s payload is used and a small power penalty for each additional recirculation, up to 10 recirculations, is achieved. Introduction: Contention resolution in optical switching can be addressed using both fibre delay lines(More)
Optical threshold functions are a basic building block for all-optical signal processing, and this paper investigates a threshold function design reliant on a single active element. An optical threshold function based on nonlinear polarization rotation in a single semiconductor optical amplifier is proposed. It functions due to an induced modification of(More)
This paper considers the performance of an all-optical packet-switched cross-connect. All-optical header processing and all-optical routing are implemented in the cross-connect architectures. The main metric considered to measure the performance is the packet loss ratio for the buffering. This is influenced primarily by three factors. The first is the(More)
Multiple recirculations through an optical buffer using a fast-reconfigurable AVC based Crosspoint switch matrix is shown. A 10Gbit/s payload is used and a small power penalty for each additional recirculation is achieved. Introduction Contention resolution in optical switching can be addressed using both fibre delay lines (FDLs) and the wavelength domain.(More)
