Role of AlGaN back-barrier in enhancing the robustness of ultra-thin AlN/GaN HEMT for mmWave applications

N. Said, Kathia Harrouche, F Medjdoub, N. Labat, Jean-Guy Tartarin, N. Malbert

In this work, the robustness of three different AlN/GaN structures targeting high frequency applications with ultra-thin 3 nm AlN barrier and devices with different gate-to-drain spacing are evaluated. Devices were step-stress tested in off-state, semi-on-state, and on-state conditions. Different...

Ultra-hydrophobic biomimetic transparent bilayer thin film deposited by atmospheric pressure plasma

Manon Saget, Nicolas Nuns, Philippe Supiot, Corinne Foissac, Séverine Bellayer, Kevin Dourgaparsad, Pierre-Alexandre Royoux, Guillaume Delaplace, Vincent Thomy, Yannick Coffinier, Maude Jimenez

An open-air atmospheric pressure plasma was used to deposit ultrahydrophobic bilayer coatings. The plasma setup was tuned, allowing the successive injection in the post-discharge of two monomers. To the best of our knowledge, no study describes the successive deposition by atmospheric plasma of two...

Photonic THz mixers based on iron-doped InGaAs embedded in a plasmonic microcavity

Charbel Tannoury, Victor Merupo, Giuseppe Di Gioia, Vanessa Avramovic, David Troadec, Jean-François Lampin, Guillaume Ducournau, Steffen Breuer, Björn Globisch, Stefano Barbieri, Robert B Kohlhaas, Emilien Peytavit

We present an optoelectronic mixer for the terahertz (THz) frequency-domain based on an iron-doped InGaAs layer integrated in a plasmonic microcavity. We show that this structure, under 1550-nm-wavelength illumination, allows for more than 70% absorption efficiency in a 220 nm-thin InGaAs absorber...

CW Laser Emission up to 5 THz Using Optically Pumped Water Molecules

L. Juppet, A. Khabbaz, Gaël Mouret, Jean-Francois Lampin, Olivier Pirali

In this work we discuss the use of a new molecule (deuterated water, D 2 O) to produce THz radiation using a midinfrared quantum cascade laser (MIR-QCL) pumped molecular laser. The molecular gain factor was used to determine the most favorable laser lines and several laser lines were measured up to...

High precision molecular laser frequency measurements using a THz frequency comb

A. Khabbaz, L. Juppet, O. Pirali, Jean-Francois Lampin, Francis Hindle, Gaël Mouret

Molecular lasers are powerful sources of continuous-wave THz radiation that can be used as local oscillators for heterodyne receivers. In this work we show that it is possible to measure precisely their emission frequency using a simple setup based on a THz frequency comb referenced to a microwave...

Développement d’une interface utilisateur interactive pour l’enseignement du traitement de signal

Nikolay Smagin, Lynda Chehami

Dans l'apprentissage de traitement du signal, les connaissances formelles (théorèmes et lois) se fait généralement en lien avec la pédagogie dans le souci de mieux les faire appréhender et assimiler par les étudiants. Ces concepts fondamentaux sont parfois difficiles à enseigner dans le schéma...
