Abstract: Single-mode lasing of quantum-cascade lasers with a distributed Bragg reflector formed by ion-beam etching in layers of the upper waveguide cladding is demonstrated. The active region is formed based on an In$_{0.53}$Ga$_{0.47}$As/Al$_{0.48}$In$_{0.52}$As solid-alloy heteropair with two-phonon depletion of the lower level in the cascade. Single-mode lasing at a temperature of 280 K corresponds to the emission wavelength of 7.74 $\mu$m, and the side-mode suppression ratio is 24 dB.

Keywords: superlattice, quantum-cascade laser, epitaxy, indium phosphide.
