Abstract
Distributed Bragg reflector Pb1−xSnxSe/Pb1−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.This publication has 0 references indexed in Scilit:
