Single-frequency lasing of quantum-cascade lasers with a distributed Bragg reflector formed by the focused ion beam milling technique in the layers of the upper cladding of the waveguide is demonstrated. The active region In0.53Ga0.47As/Al0.48In0.52As is formed based on the scheme with two-phonon lower energy level depopulation in the cascade. Single-frequency lasing at a temperature of 280 K corresponded to a radiation wavelength of 7.74 μm; the side mode suppression ratio (SMSR) was 24 dB.

Abstract In this paper, an anomalous spectral data of distributed Bragg reflector (DBR) quantum cascade lasers (QCLs) emitting around 7.6 μm is presented. The two-section DBR lasers, consisting of a gain section and an unpumped Bragg reflector, display an output power above 0.6 W in continuous wave (CW) mode at room temperature. The anomalous spectral data is defined as a longitudinal mode which moves toward shorter wavelengths with increasing temperature or injection current, which is unexpected. Although the longer wavelength modes are expected to start lasing when raising device temperature or injection current, occasional mode hops to a shorter wavelength are seen. These anomalous mode transitions are explained by means of modal analysis. The thermal-induced change of the refractive index implied by an increase in the temperature or injection current yields nearly periodic transitions between cavity modes.
