High-resolution THz gain measurements in optically pumped ammonia

Martin Mičica, Sophie Eliet, Mathias Vanwolleghem, Roman Motiyenko, Anastasia Pienkina, Laurent Margulès, Kamil Postava, Jaromír Pištora, Jean-Francois Lampin

This study is aimed at the evaluation of THz gain properties in an optically pumped NH$_3$ gas. NH$_3$ molecules undergo rotational-vibrational excitation by mid-infrared (MIR) optical pumping provided by a MIR quantum cascade laser (QCL) which enables precise tuning to the NH3 infrared transition...

Device-free human activity microwave detection

Kamel Haddadi, Christophe Loyez

This work describes a device-free activity detection method using a 2.45 GHz link associated to a short-time Fourier transform algorithm. Detection of human activities are exemplary demonstrated to validate the proposed approach considering several scenarios. The simplicity of hardware/software...

Electron and Hole g-Factors and Spin Dynamics of Negatively Charged Excitons in CdSe/CdS Colloidal Nanoplatelets with Thick Shells

Elena V. Shornikova, Louis Biadala, Dmitri R. Yakovlev, Donghai Feng, Victor F. Sapega, Nathan Flipo, Aleksandr A. Golovatenko, Marina A. Semina, Anna V. Rodina, Anatolie Mitioglu, Mariana V. Ballottin, Peter C. M. Christianen, Yuri G. Kusrayev, Michel Nasilowski, Benoit Dubertret, Manfred Bayer

We address spin properties and spin dynamics of carriers and charged excitons in CdSe/CdS colloidal nanoplatelets with thick shells. Magneto-optical studies are performed by time-resolved and polarization-resolved photoluminescence, spin-flip Raman scattering and picosecond pump-probe Faraday...

Miniaturized Coplanar Waveguide for Nanostructured Magnetostrictive Multilayer Characterization

Abdelhatif El Fellahi, Aurélien Mazzamurro, Jean Claude Gerbedoen, Yannick Dusch, Olivier Bou Matar, Philippe Pernod, Abdelkrim Talbi, Nicolas Tiercelin

A miniaturized coplanar waveguide (CPW) on a Y-cut LiNbO3 substrate operating in Radio Frequency region (RF) is proposed for studying of magnetostrictive multi-layered structure. The structure is composed of a 14 × [TbCo2 (3.7 nm)/FeCo (4 nm)] nanostructured multi-layer. Using microtechnology...
