Infrared photonics for healthcare: A roadmap for proactive and predictive health management
Borislav Hinkov, Johannes Kunsch, Werner Mäntele +82
The field of infrared (IR) photonics is currently undergoing remarkable progress, moving rapidly towards practical sensing applications demanded by medical therapy and diagnostics…
Epitaxial growth optimization, measurement and theoretical analysis of strain-compensated QCL grown on (511)A InP
Alessio Cargioli, Mattias Beck, Jerome Faist
Interface roughness scattering is an important limiting factor for achieving high performance Quantum Cascade Lasers. Following recent results, we study the growth conditions for a…
Metasurface-Enhanced Mid-Infrared Imaging Spectroscopy with Broadband Quantum Cascade Lasers
Ivan Sinev, Alessio Cargioli, Diego Piciocchi +3
Mid-infrared (mid-IR) spectroscopy offers unparalleled opportunities in sensing through chemically specific detection of molecular absorption fingerprints. Yet, its practical appli…
Quantum Walk Comb in a Dual Waveguide Quantum Cascade Laser
Alessio Cargioli, Miguel Montesinos Ballester, Sonja Gantner +3
Ring quantum cascade lasers (QCLs) proved to be a versatile tool for generating tunable and stable frequency combs in the mid infrared range in the form of quantum walk combs. By h…
Quantum Cascade Lasers as Broadband Sources via Strong RF Modulation
Alessio Cargioli, Diego Piciocchi, Mathieu Bertrand +5
In this work, we demonstrate that in a regime of strong modulation, by generating pulses of the length of the order of a few cavity lifetimes (hundreds of ps), a broadband quantum…
