Abstract
Distributed Bragg reflector Pb1-xSnxSe/Pb 1-x-yEuySnxSe double heterostructure stripe geometry diode lasers were fabricated using molecular-beam epitaxy. Single-mode cw operation at about 7.8 μm was obtained for heat-sink temperatures in the range 25-75 K. the single-mode continuous tuning range was 10 cm -1. Tuning the diodes via the injection current, a range of 24 cm-1 was completely covered with single-mode emission. The reason for this wide tuning range was mode hopping to lower frequencies rather than the usual hopping to higher frequencies.
