Description: he fabrication and performaince of a semiconductor
optical amplifier for wavelength conversion in subcarrier
multiplexed system is described. The amplifier is of the buried
facet design and has p o ~ a r ~ ~ a ~anido nre flectivity gain ripple of
carrier multiplexing, multiple 50-Mb/s
data streams at a wave~ength of 1.553 pm are injected into the
amplifier. The gain y of the amplifier transfers the
data to a dierent w of light siniultaneously injected
into the amplifier. Error free retri of subcarrier multiplexed
data has been de~ons~ratefodr the wavelength converted output.
The small signal bandwidth of the wavelength conversion process
is 5 GHz.
