Abstract
The dynamic gain properties of a serial structure of C+L wide-band EDFA are investigated. It is found out that changing of C band (L band) signal has almost no effect on the gain spectra of L band (C band), so that dynamical gain control can be realized by mature fast linear pump control via monitoring of C band and L band input signal respectively. The method was demonstrated experimentally for the first time.
