Over the past decade, the demonstration of frequency combs has been reported in a wide
range of quantum cascade lasers. These combs have huge potential in applications …

The dynamics of semiconductor lasers with fast gain is generally considered to suppress
amplitude modulation, resulting in a frequency‐modulated output. Since their first …

Wave instability—the process that gives rise to turbulence in hydrodynamics—represents
the mechanism by which a small disturbance in a wave grows in amplitude owing to …

Quantum cascade lasers (QCLs) constitute an intriguing opportunity for the generation of on-
chip optical dissipative Kerr solitons (DKSs). Originally demonstrated in passive …

<? TeX 0pt-46pc?> Electro-optic quantum coherent interfaces map the amplitude and phase
of a quantum signal directly to the phase or intensity of a probe beam. At terahertz …

We present homogeneous quantum cascade lasers (QCLs) emitting around 3 THz which
display bandwidths up to 950 GHz with a single stable beatnote. Devices are spontaneously …

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 …

Optical frequency combs (OFCs), which establish a rigid phase-coherent link between the
microwave and optical domains of the electromagnetic spectrum, are emerging as key high …

Harmonic frequency combs, in which the lasing modes are separated by a period of tens of
free spectral ranges from each other, have been recently discovered in quantum cascade …

Laser dynamics encompasses universal phenomena that can be encountered in many
areas of physics, such as bifurcation and chaos, mode competition, resonant nonlinearities …
