Reflective Semiconductor Optical Amplifier Pulse Propagation Model [PDF]
IEEE Photonics Technology Letters, 2012 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 ...

Modeling reflective bistability in vertical-cavity semiconductor optical amplifiers [PDF]
IEEE Journal of Quantum Electronics, 2005 The characteristics of optical bistability in a vertical cavity semiconductor optical amplifier (VCSOA) operated in reflection are reported. The dependences of the optical bistability in VCSOAs on the initial phase detuning and on the applied bias current are analyzed.
