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…
First-order thermal insensitivity of the frequency of a narrow spectral hole in a crystal
S. Zhang, S. Seidelin, R. Le Targat +3
The possibility of generating an narrow spectral hole in a rare-earth doped crystal opens the gateway to a variety of applications, one of which is the realization of an ultrastabl…
Causality and instability in wave propagation in random time-varying media
Romain Pierrat, Julia Rocha, Rémi Carminati
We develop a theoretical model to investigate wave propagation in media with random time-varying properties, where temporal fluctuations lead to complex scattering dynamics. Focusi…
Temperature-dependent mechanical losses of Eu:YSiO for spectral hole burning laser stabilization
Nico Wagner, Johannes Dickmann, Bess Fang +2
We investigate the mechanical loss characteristics of Eu:YSiO$\unicode{x2013}$a promising candidate for ultra-low-noise frequency stabilization through the spectral…
Hybridization of terahertz phonons and magnons in disparate and spatially-separated material specimens
Marcin Białek, Yanko Todorov, Kamil Stelmaszczyk +6
The interaction between light and matter in condensed matter excitations and electromagnetic resonators serves as a rich playground for fundamental research and lies at the core of…
