Purcell enhanced electroluminescence of a unipolar light emitting quantum device at 10 micron
Marta Mastrangelo, Djamal Gacemi, Axel Evirgen +7
Efficient generation of radiation in the mid- and far- infrared relies primarily on lasers and coherent nonlinear optical phenomena driven by lasers. This wavelength range lacks of…
Accurate prediction of optical transitions in epitaxial InGaAs/InAlAs asymmetric coupled quantum well structures
Konstantinos Pantzas, Virginie Trinité, Angel Vasanelli +5
Atomically-resolved Z-contrast and strain mappings are used to extract a model of the composition of an InGaAs/InAlAs asymmetric coupled quantum-well structure grown on InP using m…
Mid-Infrared Frequency Combs and Pulse Generation based on Single Section Interband Cascade Lasers
Pavel Abajyan, Baptiste Chomet, Daniel A. Diaz-Thomas +10
Interband Cascade Lasers (ICLs) are semiconductor lasers emitting in the mid-wave infrared (MWIR 3-6 μm) and can operate as frequency combs (FCs). These demonstrations are based o…
Heterodyne coherent detection of the electric field temporal trace emitted by frequency-modulated comb lasers
Baptiste Chomet, Salim Basceken, Djamal Gacemi +6
Frequency-modulated (FM) combs are produced by mode-locked lasers in which the electric field has a linearly chirped frequency and nearly constant amplitude. This regime of operati…
Ultra-sensitive heterodyne detection at room temperature in the atmospheric windows
Mohammadreza Saemian, Livia Del Balzo, Djamal Gacemi +9
We report room temperature heterodyne detection of a quantum cascade laser beaten with a local oscillator on a unipolar quantum photodetector in two different atmospheric windows,…
