Abstract: An EDF amplifier comprises two EDF loops separated by optical isolators and pumped with light by pump laser diodes under the control of an output power control system. To achieve the required output power the current supplied to the pump supplying light to the input loop is set to the maximum drive current Imax for the pump laser, and the pump currents of all pumps not supplying light to the input loop, that is the pumps supplying light to the further loop or loops, are adjusted to achieve the required output power. To avoid a very high MPI, the inversion of all loops is never so low that the gain in the first loop has to compensate for loss in the following loop or loops. This is done by providing a minimum pump power to the second loop and any following loops. This ensures that the loops are always inverted enough, and that they do not exhibit too much loss. The required minimum pump current is obtained by modelling and experimental verification.

Abstract: A gain-flattening filter for in-line compensation of the spectral gain profile of an optical amplifier comprises: a first GFF component having a transmission curve with a spectral loss profile corresponding to the spectral gain profile of an optical amplifier, and a second GFF component having a transmission curve with a spectral loss profile corresponding to the error function of the first GFF component.
