Abstract
Laterally coupled, complex distributed feedback lasers based on InAs/InGaAs/InAlGaAs/InP quantum dash-in-a-well layers emitting in the 1.9 mu m wavelength range were fabricated. Total CW powers above 25 mW at room temperature and sidemode suppression ratios of more than 35 dB are demonstrated, which makes the devices promising for gas sensing applications.
