Abstract :
Summary form only given. In this paper we elaborately apply the beam propagation method (BPM) to allow for the more appropriate superposition of the optical fields in the InGaAs-GaAs QW active semiconductor laser amplifer device. With the inclusion of the lateral phase variations we are able to study the impacts of residual facet reflectivities on the performance characteristics of traveling wave amplifiers in detail.
