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…

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,…
