S. Scotti et A. Mecozzi, FREQUENCY-CONVERTERS BASED ON FWM IN TRAVELING-WAVE OPTICAL AMPLIFIERS - THEORETICAL ASPECTS, Fiber and integrated optics, 15(3), 1996, pp. 243-256
We summarize the results of a theoretical model, developed to investig
ate the performance of a frequency converter based on four-wave mixing
in a bulk traveling wave amplifier The theory predicts very high valu
es of conversion efficiency and signal-to-background ratio in the band
width of the converted signal. These results, whose experimental confi
rmation is reported elsewhere, increase the potential of using four-wa
ve mixing in semiconductor amplifiers in actual optical systems.
