Abstract:
The calculation of dielectric mirrors for quantum cascade lasers in the mid-IR range was carried out. Optimal dielectric materials were selected to minimize the absorption of laser radiation. Samples of quantum cascade lasers emitting within the spectral range of 4 – 5 μm with various dielectric highly reflective mirror coatings were made and their characteristics were studied. It was shown that the deposition of highly reflective Si – Si3N4 coating on the rear face of the resonator led to the increase in the output optical power of the lasers under study by 71% as compared to the control samples without coatings. The use of Si – SiO2 coating made it possible to increase the output power of the emitters by 88%.
Keywords:
quantum cascade laser, highly reflective mirrors, output power, infrared range.
