Mid-IR single- and dual-electro-optic comb generation with an ultrafast modulator
Gia-Long Ngo, Luca Lucia, Stefano Pirotta +9
Mid-infrared (mid-IR) frequency combs are powerful tools for molecular sensing, industrial monitoring, and precision spectroscopy, yet their development beyond 5 um remains limited…

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,…
