Km. Guild et Mj. Omahony, DUAL-WAVELENGTH CONVERTER ARCHITECTURE IN ALL-OPTICAL PACKET-SWITCHEDROUTING NODE, Electronics Letters, 34(21), 1998, pp. 2047-2048
The authors describe an architecture for an all-optical packet-switche
d routing node which eliminates the detrimental effects of intra-band
crosstalk arising from filterless wavelength converters employing cros
s-gain modulation in semiconductor optical amplifiers. A dual-stage wa
velength conversion scheme and an arrayed-waveguide grating for optica
l routing demonstrates < 0.9dB power penalty for 800Mbit/s payloads.
