Quantum cascade laser-based Kerr frequency comb generation
Tobias Kippenberg, Clément Christian Javerzac-Galy, Erwan Guillaume Albert Lucas, John David Jost, Caroline Marie Anne Lecaplain
We report mid-infrared Kerr comb generation based on a quantum cascade laser pumping a crystalline microresonator. For the first time QCL light is coupled into a microresonator via a tapered chalcogenide fiber allowing mid-IR Kerr comb generation. ...
Ieee Computer Soc2016Optimization of NH₃-MBE grown p-doped (Al)GaN layers and their implementation in long wavelength laser diodes and tunnel junctions
Over the last two decades III-nitride optoelectronic devices have experienced an impressive evolution in terms of performance. However, their potential is far from being fully exploited. Although they offer bandgaps from the deep UV to the infrared spectra ...
EPFL2015GaN-based photonic crystal cavities on silicon for visible and near infrared applications
Photonic crystal (PhC) cavities combine ultra-high quality (Q) factors with small mode volumes, resulting in an enhancement of the light-matter interaction at the nanoscale, which, beyond fundamental studies is advantageous for countless applications in ph ...
EPFL2015Light Generation and Harvesting in a van der Waals Heterostructure
Aleksandra Radenovic, Andras Kis, Esther Alarcon Llado, Oriol López Sánchez, Volodymyr Koman
Two-dimensional (2D) materials are a new type of materials under intense study because of their interesting physical properties and wide range of potential applications from nanoelectronics to sensing and photonics. Monolayers of semiconducting transition ...
Amer Chemical Soc2014InGaN alloys and heterostructures
The III-nitride semiconductor material system - (InAlGa)N - is of highest interest for optoelectronic applications due to its direct bandgap, tunable from the ultraviolet to the infrared spectral range. The most well-known are white light-emitting diodes, ...
EPFL2014Cocaine detection in liquid using a fibred platform and mid-infrared quantum cascade laser
Hans Peter Herzig, Grégoire Maxime Smolik, Lubos Hvozdara, Joab Di Francesco
A miniaturized, trace level sensor for cocaine is presented. A quantum cascade laser emitting at 1720 cm-1 is coupled to a fibred absorption flow-cell. A detection limit lower than 250 ng/mL (84 ppb) is reported. ...
2014Dilute-Nitride Low-Dimensional Nanostructures Formed on Non-Planar Substrates
The properties of semiconductors heterostructures of nanoscopic dimensions change from that of bulk material according to the rules of quantum mechanics. The planar quantum wells (QWs) are widely used in various diode and laser devices thanks to the relati ...
