摘要
The dynamics of nonlinear processes in quantum dot (QD) semiconductor optical amplifiers investigated. Using small-signal measurements, the suitabilities of cross-gain and cross-phase as well as four wave mixing (FWM) for wavelength conversion are examined. The cross-gain is found to be suitable for wavelength conversion up to a frequency of 40 GHz. (SOAs) are modulation modulation
