Abstract

We proposed a simultaneous three-wavelength conversion based on the cross-gain modulation (XGM) in the multi-wavelength semiconductor fiber ring laser (SFRL). It is easily implemented owing to the simple structure. Furthermore, it has realized multi-channel wavelength conversion, which reduces the cost of network expansion. A comprehensive broadband dynamic model is presented. By numerical simulation, the proposed multi-wavelength conversion is theoretically realized using the broadband dynamic model. Moreover, the dependences of conversion efficiency and extinction ratio on the input signal power, signal wavelength and injection current are investigated in detail.
