Title: Fabrication and characteristics of improved strained quantum-well GaInAlAs gain-coupled DFB lasers
Abstract: Results of improved 1.58 μm GaInAlAs strained quantum-well gain-coupled DFB lasers are presented. Besides the excellent spectral properties (singlemode yield of 75% and a sidemode suppression ratio of 45 dB), 20 mW output power and CW operation at 80%C have been obtained. A record 3 dB bandwidth of 11 GHz was measured. Spectral or dynamical instabilities due to the loss grating have not been observed.
