Abstract
A method is introduced for small signal gain measurement in a low-saturation regime using an amplified spontaneous emission (ASE) footprint of a gain media. By this method, the ratio of intensities, with and without a reflector, is measured beside the bandwidth of the ASE, hence two equations are formed. An iterative solution of these equations will simultaneously determine both the small signal gain and the loss.
