Fast and high-resolution Fourier transform spectrometers are indispensable for cutting-edge infrared spectroscopy. In this study, the authors employed a newly-designed fast-rotating retroreflective, broadband delay line demonstrating fast dual-comb s

A novel study on harmonic frequency combs emitted by quantum cascade lasers (QCLs) is presented here, demonstrating the presence of intensity correlations between twin modes characterizing the emission spectra. These originate from a four‐wave mixi

We analyze theoretically a superlattice structure proposed by A. Andronov et al. [JETP Lett. 102, 207 (2015)] to give Terahertz gain for an operation point with positive differential conductivity. Here we confirm the existence of gain and show that a

Dissipative Kerr solitons are self-organized optical waves arising from the interplay between Kerr effect and dispersion. They can form spontaneously in nonlinear microresonators pumped with an external continuous-wave laser, which provides the param

Fast (sub-second) spectroscopy with high spectral resolution is of vital importance for revealing quantum chemistry kinetics of complex chemical and biological reactions. Fourier transform (FT) spectrometers can achieve high spectral resolution and o

We demonstrate the presence of intensity correlation in the harmonic comb emitted by quantum cascade lasers, paving the way for a deeper understanding of the role of the four-wave-mixing process enabling this emission.

In this work, we demonstrate the generation of 630 fs, 4.5 W pulses from a mid-infrared quantum cascade laser by gain modulation induced spectral broadening and external pulse compression. Such sources open new pathways for broadband supercontinuum g

The linewidth enhancement factor (LEF) describes the coupling between amplitude and phase fluctuations in a semiconductor laser and has recently been shown to be a crucial component for frequency comb formation in addition to linewidth broadening. It

Semiconductor material systems based on GaAs or InP are excellent candidates for optoelectronics in the mid-IR to terahertz spectral range. Consequently, they have readily been used for devices like THz quantum cascade lasers (QCLs) in recent years.
