We report on an all-optical demultiplexer based on gain-transparent operation of a semiconductor optical amplifier (SOA) in an ultrafast-nonlinear interferometer (GT-UNI). The GT-UNI comprises a robust fiber-chip setup in a folded geometry. For switching window widths of 5.2 ps and 6.0 ps, error-free demultiplexing of 160-10 Gb/s is demonstrated

KRAJINOVIC Dynamic high-speed access to optical fiber can be achieved by transmitting data at a very high bit rate in a packet-switched manner. Access nodes, which are able to process high-speed optical packets and to provide fast switching in the optical domain, are the scope of this paper. All-optical techniques for short pulse generation and transmission, dispersion compensation, data rate conversion, clock recovery and header processing are described and discussed.

Abstract:An optical packet compression/decompression scheme applicable in ultrahighspeed OTDM networks is proposed. This full-extensible scheme allows high compression rates and !arge packet sizes by relaxing the medium access constrains. The improvement of the Optical Packet Compression-TDM (OPC-TDM) network performance achieved by reducing the rate-conversion latency is shown.
