Molecular beam epitaxy techniques were used to grow a quantum-cascade laser (QCL) heterostructure based on an In{sub 0.53}Ga{sub 0.47}As/Al{sub 0.48}In{sub 0.52}As heteropair lattice-matched with an InP substrate. InP layers were used to form an optical waveguide. The obtained QCL heterostructure ensured room-temperature lasing in the 8-μm wavelength range at a maximum output optical power of 0.45 W from one facet in a standard ridge geometry of the Fabry–Pérot cavities formed by cleaved facets.
