Dual-comb spectroscopy (DCS) is a promising approach for real time, high precision, and
high sensitivity Fourier-transform spectroscopy. DCS requires a pair of tightly phase-locked …

Neutral quantum absorbers in optical lattices have emerged as a leading platform for
achieving clocks with exquisite spectroscopic resolution. However, the studies of these …

Recently, the field of optical frequency combs experienced a major development of new
sources. They are generally much smaller in size (on the scale of millimetres) and can …

Quantum cascade lasers (QCLs) represent the most fascinating achievement of quantum
engineering, showing how artificial materials can be generated through quantum design …

Four-wave-mixing-based quantum cascade laser frequency combs (QCL-FC) are a powerful
photonic tool, driving a recent revolution in major molecular fingerprint regions, ie mid-and …

We present a study concerning the dynamics of dense and harmonic coherent regimes in
quantum cascade lasers (QCLs) in a Fabry–Perot configuration emitting in the terahertz …

The ability to engineer quantum-cascade-lasers (QCLs) with ultrabroad gain spectra, and
with a full compensation of the group velocity dispersion, at terahertz (THz) frequencies, is …

Broadband, quantum-engineered, quantum cascade lasers (QCLs) are the most powerful
chip-scale sources of optical frequency combs (FCs) across the mid-infrared and the …

Optical metrology and high-resolution spectroscopy, despite impressive progress across
diverse regions of the electromagnetic spectrum from ultraviolet to terahertz frequencies, are …
