Abstract
The degradation of the side-mode suppression ratio (SMSR) in an integrated DFB laser and semiconductor optical amplifier (SOA) cavity is investigated. A numerical model combining finite element calculations in the x-y plane and a longitudinal model based on the Green's function approach is used for that purpose. An expression is derived that expresses the degradation of the SMSR in the case of a perfectly AR-coated SOA facet. It is shown that the ASE backcoupling can have dramatic effects and degrade and SMSR of single-mode devices to unacceptable levels.
