Abstract
The improved performance of gain-coupled DFB lasers incorporating a ti tanium surface Bragg grating and a strained layer multiquantum well ac tive region for operation at 1.55 mu m is presented. Besides the essen tially simplified fabrication process, the incorporation of the metall ic, absorptive grating yields stable singlemode operation with a high sidemode suppression.
