P. Spano et al., FREQUENCY-CONVERSION IN SEMICONDUCTOR-LASERS AND AMPLIFIERS, European transactions on telecommunications and related technologies, 5(4), 1994, pp. 517-527
Different methods to obtain frequency conversion in optical systems us
ing nonlinear effects in semiconductor devices are analyzed and discus
sed. In particular, some recent results obtained on the frequency conv
ersion by gain saturation and four wave mixing (FWM) in semiconductor
lasers and amplifiers are reported.
