Abstract
A spectrometer device may include a first QCL configured to operate in a frequency comb mode with spectrally equidistant modes with stable relative phase, a power supply coupled to the first QCL, and a controller coupled to the power supply. The first QCL may include different active region layers based on a vertical transition. The first QCL may be configured to provide a comb output having a cumulative flat gain profile and reduced dispersion refractive index profile in a broad range of driving conditions. The spectrometer device may include a sample cell configured to receive the comb output.
