© 2022, Pleiades Publishing, Ltd.Abstract—: The design of a terahertz (THz) quantum cascade laser (QCL) with an active module based on three GaAs/Al0.18Ga0.82As quantum wells for high-temperature generation at a frequency of about 3.3 THz is optimized. A heterostructure based on the developed design with an active region thickness of 10 μm is grown by molecular-beam epitaxy with a deviation of the active-module thickness from the nominal of less than 1%. The fabricated THz QCLs with a double metal waveguide demonstrate lasing up to a temperature of 125 K. Investigations of the I–V characteristics, the dependences of the integrated emission on the current, and the lasing spectra show good agreement with the calculated characteristics.
