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…
Heterodyne coherent detection of phase modulation in a mid-infrared unipolar device
Hamza Dely, Baptiste Chomet, Thomas Bonazzi +8
Phase modulation is demonstrated in a quantum Stark effect modulator designed to operate in the mid-infrared at wavelength around 10 m. Both phase and amplitude modulation are s…
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,…
Highly coherent phase-lock of an 8.1 m quantum cascade laser to a turn-key mid-IR frequency comb
B. Chomet, D. Gacemi, O. Lopez +5
A continuous-wave Fabry-Perot quantum cascade laser (QCL) emitting at 8.1 m operating in the single mode regime has been coherently phase locked to a turn-key low-noise commerci…
10 Gbit/s free space data transmission at 9 m wavelength with unipolar quantum optoelectronics
Hamza Dely, Thomas Bonazzi, Olivier Spitz +12
The realization of high-frequency unipolar quantum optoelectronic devices enables the demonstration of high bitrate free space data transmission in the second atmospheric window. D…
