Distributed feedback PbSnSe/PbEuSnSe double heterostructure stripe geometry diode lasers were fabricated using molecular beam epitaxy. These lasers operated in cw mode up to 90 K and in the pulse mode up to 100 K. They were unique in their low tuning rate with injection current 4 cm-1/A, and in that they withstood high cw injection currents without damage. These features are probably the results of the metal cladding layer located on top of the gratings.
