Dynamically reconfigurable THz quantum walk comb laser through subharmonic excitation
Valerio Digiorgio, Robert Matthew Gray, Marco Raffa +5
On-chip frequency combs are increasingly relevant to both laser science and applications. Broad bandwidths and flat-top spectral envelopes are especially desirable for precision sp…
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…
Free-Running Ring Quantum Cascade Laser with 50 kHz Linewidth
Alexandre Parriaux, Ina Heckelmann, Mathieu Bertrand +3
We report on the noise characterization of a free-running ring quantum cascade laser resonator emitting a single frequency mode around 7.7 m. Using a gas cell filled with NO…
Fast and compact time-resolved spectroscopy enabled by Quantum Walk Combs
Ina Heckelmann, Davide Pinto, Uwe Schmitt +2
Optical frequency combs paved the way for fast and compact multi-component optical chemical analysis due to their broadband spectra. Dual-comb spectrometers embody this technology,…
Integrated thin film lithium niobate mid-infrared modulator
Pierre Didier, Prakhar Jain, Mathieu Bertrand +7
The mid-infrared spectral range holds great promise for applications such as molecular spectroscopy and telecommunications. Many key molecules exhibit strong absorption features in…
Ultrafast Non-Hermitian Skin Effect
Barbara Schneider, Alexander Dikopoltsev, Markus Bestler +5
Topological phases of matter commonly feature protected states at their boundaries. Transferring this protection to time-metamaterials is extremely challenging, as it requires the…
Non-resonant Optical Injection Locking in Quantum Cascade Laser Frequency Combs
Alexandre Parriaux, Kenichi N. Komagata, Mathieu Bertrand +4
Optical injection locking of the repetition frequency of a quantum cascade laser frequency comb is demonstrated using an intensity modulated near-infrared light at 1.55 m illumi…
Microring quantum cascade surface emitting lasers
David Stark, Mattias Beck, Jérôme Faist
We miniaturize a vertically-coupled in-plane whispering gallery mode cavity incorporating a quantum cascade gain medium, aiming to realize the mid-infrared counterpart to the verti…
