description: The given work is devoted to exploring possibility of single-mode operation using quantum-cascade lasers at room temperature. It investigates lasers with plane-parallel cavity and arched cavity. Laser structures were grown by Connector Optics LLC. Current-voltage characteristics and light-intensity-current-voltage characteristics were measured. Lasing spectra were measured at different current using Fourier-transform spectrograph. Threshold currents and operation ranges were determined. Refractive indexes in Fabry-Perot cavity lasers were measured. Acquired data will help in calculating parameters of lasers with more complicated types of resonators. All the results can be used in further improvement of quantum-cascade lasers design. This type of lasers is essential at mid- and far-infrared wavelength range. It ensures the importance of present research.
