Reflective Semiconductor Optical Amplifier Pulse Propagation Model [PDF]
IEEE Photonics Technology Letters, 2011 A simple time-domain model for optical pulse propagation in a reflective semiconductor optical amplifier (RSOA) is described. The RSOA saturation energy, effective carrier lifetime and spectral hole-burning parameters used in the model are determined using experimental measurements of the input and output pulse temporal profiles to the RSOA and least ...
