Distributed Bragg reflector (DBR) lattice-matched Pb/sub 1-x/Sn/sub x/Te/PbSe/sub y/Te/sub 1-y/ diode lasers were fabricated using liquid phase epitaxy. These DBR lasers were operated within a limited range of heat-sink temperatures 8.5--38 K, and the threshold current density at 20 K was approx.3 kA/cm/sup 2/. Single longitudinal-mode operation was obtained up to more than three times the threshold current. The DBR lasers exhibited continuous tuning over a relatively wide range of approx.6 cm/sup -1/ near 775 cm/sup -1/ (12.9 ..mu..m). The average tuning rate was 0.21 cm/sup -1//K, and it was much smaller than the rate for corresponding Fabry--Perot lasers, which was 2.3 cm/sup -1//K.
