Jpr. Lacey et al., 4-CHANNEL WDM OPTICAL-PHASE CONJUGATOR USING 4-WAVE-MIXING IN A SINGLE SEMICONDUCTOR OPTICAL AMPLIFIER, Electronics Letters, 31(9), 1995, pp. 743-744
Multichannel optical phase conjugation in a semiconductor optical ampl
ifier (SOA) is reported. A single SOA is used to conjugate four 2.5Gbi
t/s WDM channels with 2nm channel spacings. Our results show that pena
lties due to crosstalk between channels during conjugation can be acce
ptably small.
