Abstract

The problem of the linewidth degradation in systems using distributed-feedback lasers together with strained-layer multi-quantum-well semiconductor optical amplifiers (SOAs) is examined. A numerical model combining finite element calculations in the transverse x - y plane and a longitudinal model based on the Green's function method is used for that purpose. Simple expressions for the linewidth in the case of AR-coated SOA output facets are derived and simulation results are given in the case of an output facet with a non-vanishing reflectivity. It is found that optimal conditions for a narrow linewidth can be determined.
