The design, fabrication, and testing of distributed Bragg reflector (DBR), distributed feedback (DFB), and grating coupled emission (GCE) Pb/sub 1-x/Sn/sub x/Se/Pb/sub 1-x-y/Eu/sub y/Sn/sub x/Se double heterostructure stripe geometry molecular-beam-epitaxy (MBE) grown diode lasers are discussed. The DBR and DFB lasers are the first Pb-salt corrugated lasers to operate in CW (continuous) mode at temperatures above that of liquid nitrogen. For the GCE lasers, a narrow far field distribution of approximately 5 degrees was obtained for the first time.>
