In this article, we use a time-domain traveling-wave approach with a coupled-mode theory to describe the dynamics of a mid-Infrared (MIR) Quantum Cascade Laser (QCL) in the Distributed-Feedback (DFB) configuration. We demonstrate that linewidth enhan

We present a design of a tunable hybrid laser based on III-V Reflective Semiconductor Optical Amplifier (RSOA) and Silicon Photonics (SiPh) external mirror that represents a good trade off between high Wall-Plug Efficiency (WPE) and high tolerance to

We introduce a generalized capturing the physics of frequency combs generated from active and passive cavities. This unification opens the possibility to control the morphogenesis of patterns such as Turing rolls and temporal solitons.

Ring quantum cascade lasers generate self-starting frequency combs and dissipative cavity solitons. We present a reengineered ring resonator with an evanescent wave directional coupler that allows coherent control over laser state and enhances power

We report how external cavity III-V/Si hybrid lasers operate in regimes of ultra-damped relaxation oscillations or in turbulent and self-pulsing regimes. The different regimes are reached by detuning the lasing wavelength respect to the mirror effect

Our ability to generate new distributions of light has been remarkably enhanced in recent years. At the most fundamental level, these light patterns are obtained by ingeniously combining different electromagnetic modes. Interestingly, the modal super

Near-field imaging techniques at terahertz frequencies (0.5-10 THz), conventionally rely on bulky laser sources and detectors. Here, we devise a compact configuration for scattering near-field nanoscopy based on quantum cascade lasers (QCL) that can
