N2 - Distributed Bragg-reflector (DBR) diode lasers were de- signed and fabricated from lattice-matched Pb1-xSnxTe/PbSeyTe1-y single heterostructures grown by liquid-phase epitaxy. These DBR lasers operated in a single longitudinal mode within a limited range of heat-sink temperatures, 8.5-38 K, with a threshold current density of ~ 3 kA/cm2 at 20 K. Single longitudinal mode operation was maintained up to more than three times the threshold current. Continuous tuning of the laser output frequency over a range of ~ 6 cm-1, near 775 cm-1 (12.9 μm), was acheived by varying the heal-sink temperature. The average tuning rate was 0.21 cm-1 /K, and it was much smaller than the rate for corresponding Fabry-Perot lasers, which was 2.3 cm -1/K. The measured effective mode index of the DBR lasers agrees well with the calculated one.
