An engineered planar plasmonic reflector for polaritonic mode confinement
Shima Rajabali, Josefine Enkner, Erika Cortese +4
It was recently demonstrated that, in deep subwavelength gap resonators coupled to two-dimensional electron gases, coupling to propagating plasmons can lead to energy leakage and p…
THz optical solitons from dispersion-compensated antenna-coupled planarized ring quantum cascade lasers
Paolo Micheletti, Urban Senica, Andres Forrer +6
Quantum Cascade Lasers (QCL) constitute an intriguing opportunity for the production of on-chip optical Dissipative Kerr Solitons (DKS): self-organized optical waves which can trav…
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…
Planarized THz quantum cascade lasers for broadband coherent photonics
Urban Senica, Andres Forrer, Tudor Olariu +6
Recently, there has been a growing interest in integrated THz photonics for various applications in communications, spectroscopy and sensing. We present a new integrated photonic p…
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…
