Room-temperature continuous-wave Terahertz generation with an intersubband mid-infrared photomixer

Quyang Lin, Jean-Francois Lampin, Guillaume Ducournau, Hua Li, Emilien Peytavit, Stefano Barbieri

A Terahertz photomixer pumped by mid-infrared photons at 10µm wavelength is demonstrated. The device active-region consists of an AlGaAs-GaAs multi-quantum-well heterostructure embedded into a matrix of metallic patch-antenna resonators, electrically connected to the arms of a log-spiral antenna.…

RF-Robustness enhancement in AlN/GaN HEMT through AlGaN Back-Barrier: nonlinear model analysis

N. Said, D. Saugnon, Kathia Harrouche, Farid Medjdoub, Nathalie Labat, N. Malbert, Jean-Guy Tartarin

<div><p>In this study, we evaluate the robustness and nonlinear (NL) responses of two variants of AlN/GaN HEMT technology under RF-step stress at 10 GHz. We develop an original NL behavioral modelling approach that includes the self-biasing effect within a unique expression. This method…

Uncertainties estimation in THz-TDS experiments in transmittance, refractive index and spectroscopic parameters

Noureddin Osseiran, Jeyan Bichon, Théo Hannotte, Mouhamed Abdel-Kader, Martin Witt, Sophie Eliet, Romain Peretti

<div><p>Data processing is a key for the spreading of the THZ-TDS systems to more analytical fields. However, till today no standard methods exist to extract error bar from standard measurements in TDS besides the transmission. We propose here a methodology to reply to this challenge.…

Phonon polaritons impact atmosphere transparence in the TeraHertz range

Jeyan Bichon, Denis Petitprez, Hervé Herbin, Jean-Francois Lampin, Romain Peretti, Sophie Eliet

<div><p>Atmospheric aerosols impact the climate by modifying the radiative balance of the planet and the microphysical properties of clouds and by altering the biogeochemical balance of the atmosphere. Above all, some aerosols exhibit fascinating effects due to the phonon-polaritons…

Optimisation d'un Nano-drone à ailes vibrantes, Optimization of a Flapping-Wing Nano-Drone

Marguerite Delabigne, Eric Cattan, Sofiane Ghenna, Marie Zwingelstein, Sébastien Grondel, Olivier Thomas

L’étude du vol des insectes est une source d’inspiration pour la conception des Nano-Air Vehicles (NAVs). La compréhension du vol des insectes montre qu’il combine des mouvements de torsion et de battement. Deux approches principales existent pour concevoir des ailes de NAV : l’une utilise des…, The study of insect flight is a source of inspiration for the design of Nano-Air Vehicles (NAVs). Understanding insect flight reveals that it combines both torsional and flapping movements. Two main approaches exist for designing NAV wings: one uses rigid wings with a four-bar mechanism to amplify…
