Short period InGaAs/AlInAs THz quantum cascade laser in thin double metal cavities operating up to 188K
Sebastian Gloor, David Stark, Martin Frankié +4
We present a two-well terahertz (THz) quantum cascade laser designed for high temperature operation based on the InGaAs/AlInAs material system. The lighter effective mass and highe…
Optimization of broad gain and high optical nonlinearity of mid-infrared quantum cascade laser frequency combs
Martin Franckie
Mid-infrared Quantum Cascade Lasers (QCLs) are compact and efficient sources ideal for molecular spectroscopy applications, such as dual-comb spectroscopy. However, despite over a…
Sensitive dependence of the linewidth enhancement factor on electronic quantum effects in quantum cascade lasers
Martin Franckie, Mathieu Bertrand, Jerome Faist
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 compone…
Self-starting microring laser solitons from the periodic cubic complex Ginzburg-Landau equation
Martin Franckie
Dissipative Kerr solitons are optical pulses propagating in a nonlinear dielectric waveguide without dispersing. These attractive properties have spurred much research into integra…
Intensity correlations in quantum cascade laser harmonic frequency combs
Tecla Gabbrielli, Natalia Bruno, Nicola Corrias +10
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 charac…
Frequency chirped Fourier-Transform spectroscopy
Sergej Markmann, Martin Frankié, Mathieu Bertrand +6
Fast (sub-second) spectroscopy with high spectral resolution is of vital importance for revealing quantum chemistry kinetics of complex chemical and biological reactions. Fourier t…
Monte Carlo Modeling of Terahertz Quantum Cascade Detectors
Johannes Popp, Michael Haider, Martin Franckié +2
We demonstrate an Ensemble Monte Carlo (EMC) modeling approach for robust and rigorous simulations of photovoltaic quantum cascade detectors (QCDs) in the mid-infrared (mid-IR) and…
An electrically pumped phonon-polariton laser
Keita Ohtani, Bo Meng, Martin Franckié +4
We report a device that provides coherent emission of phonon polaritons, a mixed state between photons and optical phonons in an ionic crystal. An electrically pumped GaInAs/AlInAs…
Two-well quantum cascade laser optimization by non-equilibrium Green's function modelling
M. Franckié, L. Bosco, M. Beck +5
We present a two-quantum well THz intersubband laser operating up to 192 K. The structure has been optimized with a non-equilibrium Green's function model. The result of this optim…
