Simulation and interpretation of longitudinal-mode behavior in partly gain-coupled InGaAsP/InP multiquantum-well DFB lasers

The unique longitudinal-mode behavior observed in 1.55- mu m InGaAsP/InP partly gain-coupled multiquantum-well distributed feedback (DFB) lasers has been simulated using a transfer-matrix analysis technique. Experimental results have been successfully reproduced and interpreted according to below-threshold calculation, results.<
