Abstract: We report the results of a comparison of metal–dielectric mirror coatings for mid-IR quantum-cascade lasers (QCLs). Samples of QCLs with Al2O3/Ti/Au and SiO2/Ti/Au optical coatings are fabricated and their characteristics are studied. It is shown that the use of metal–dielectric mirror coatings allows the output optical power of devices to be increased up to 93% and their threshold currents to be reduced by 1.25 times.
Keywords: quantum-cascade laser, highly reflective mirrors, output power, IR range.
