Abstract
The authors describe an architecture for an all-optical packet-switched routing node which eliminates the detrimental effects of intra-band crosstalk arising from filterless wavelength converters employing cross-gain modulation in semiconductor optical amplifiers. A dual-stage wavelength conversion scheme and an arrayed-waveguide grating for optical routing demonstrates < 0.9 dB power penalty for 800 Mbit/s payloads.Keywords
