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…
Landau polaritons in highly non-parabolic 2D gases in the ultra-strong coupling regime
Janine Keller, Giacomo Scalari, Felice Appugliese +11
We probe ultra-strong light matter coupling between metallic terahertz metasurfaces and Landau-level transitions in high mobility 2D electron and hole gases. We utilize heavy-hole…
Broadband monolithic extractor for metal-metal waveguide based terahertz quantum cascade laser frequency combs
Markus Rösch, Ileana-Cristina Benea-Chelmus, Christopher Bonzon +4
We present a monolithic solution to extract efficiently light from terahertz quantum cascade lasers with metal-metal waveguides suitable for broadband frequency comb applications.…
Intensity autocorrelation measurements of quantum cascade laser frequency combs in the Terahertz range
Ileana-Cristina Benea-Chelmus, Markus Rösch, Giacomo Scalari +2
We report on the first direct measurement of the emission character of quantum cascade laser based frequency combs, using intensity autocorrelation. The correlation technique is ba…
