W. Shieh et Ae. Willner, A WAVELENGTH-ROUTING NODE USING MULTIFUNCTIONAL SEMICONDUCTOR OPTICALAMPLIFIERS AND MULTIPLE-PILOT-TONE-CODED SUBCARRIER CONTROL HEADERS, IEEE photonics technology letters, 9(9), 1997, pp. 1268-1270
We demonstrate wavelength routing by using the control information enc
oded in a multiple-pilot-tone subcarrier header, Header detection, hea
der removal, packet gating and wavelength shifting are all performed b
y a single multifunctional semiconductor optical amplifier (SOA). Base
d on the header information contained in the 60-ns-long pilot tones, e
ach incoming 1-Gb/s data packet either: 1) passes through the switch u
naffected or 2) is wavelength shifted and dropped at the switch.
