J. Zhou et al., BROAD-BAND WAVELENGTH CONVERSION WITH AMPLIFICATION BY 4-WAVE-MIXING IN SEMICONDUCTOR TRAVELING-WAVE AMPLIFIERS, Electronics Letters, 30(11), 1994, pp. 859-860
The authors demonstrate for the first time broadband wavelength conver
sion with amplification by four-wave mixing in semiconductor travellin
g-wave optical amplifiers and verify the cubic dependence of wavelengt
h conversion efficiency on the amplifier's single-pass optical gain.
