A comprehensive theory to investigate laser instabilities is developed. It is shown that quantum cascade lasers can display both amplitude- and phase-modulated emission, opening a promising route to ultrashort-pulse generation in the midinfrared, as well as the development of compact frequency-comb sources for spectroscopy. 

Harmonically mode-locked quantum cascade lasers for mid-infrared frequency comb generation

The single-mode to multimode transition in standing-wave quantum cascade lasers exhibits a harmonically mode-locked regime skipping cavity modes. The large sideband separation unravels a new

Self-Starting Harmonic Combs in THz Quantum Cascade Lasers

We report on high temperature, self-starting THz Quantum Cascade Laser harmonic frequency combs. Their coherence is assessed by electrical beatnote measurements and a self-mixing technique and their

Tuning the multimode dynamics of Fabry-Perot quantum cascade laser devices with optical injection

With the external injection of an optical seed, we demonstrate how to control the spectrum of multimode Fabry-Perot quantum cascade lasers by reaching a watt-level single-mode emission and tunable

Self-starting harmonic comb emission in THz quantum cascade lasers

Harmonic comb states have proven to be ubiquitous in mid-IR quantum cascade lasers. We report here on robust, pure, self-starting harmonic mode locking in Copper-based double-metal THz quantum

Intensity Correlations in Quantum Cascade Laser Harmonic Frequency Combs

A novel study on harmonic frequency combs emitted by Quantum Cascade Lasers (QCLs) is here presented, demonstrating the presence of intensity correlations between twin modes characterising the

Shaping Harmonic Frequency Combs in Ring Injection Lasers by Defect Engineering

Quantum cascade lasers are known to spontaneously skip modes and generate widely-spaced harmonic frequency combs. We show that engineering defects in a ring waveguide allows for deterministic control

Shaping harmonic frequency combs in quantum cascade lasers

Controlling the spacing of self-starting harmonic frequency combs in QCLs by design of fundamental laser parameters is arduous. New ways to shape such combs by means of original electrical, optical

Spectrally resolved modal characteristics of leaky-wave-coupled quantum cascade phase-locked laser arrays

Abstract. The modal characteristics of nonresonant five-element phase-locked arrays of 4.7-μm emitting quantum cascade lasers (QCLs) have been studied using spectrally resolved near- and far-field

Their inherently broadband gain and high value of the third order nonlinearity makes quantum cascade lasers (QCLs) ideal candidates for frequency comb generation in the terahertz (THz) and

Shortwave quantum cascade laser frequency comb for multi-heterodyne spectroscopy

Quantum cascade lasers (QCLs) are versatile light sources with tailorable emitting wavelengths covering the mid-infrared and terahertz spectral ranges. When the dispersion is minimized, frequency

TLDR
In this method, non-linear susceptibility tensors are introduced which relate the induced dipole moment to a power series expansion in field strengths and the various experimental observations are described and interpreted in terms of this formalism.
