Mechanical Enhancement of the Strain‐Sensor Response in Dimers of Strongly Coupled Plasmonic Nanoparticles

Najat Ahmidayi, William d'Orsonnens, Thomas Maurer, Gaëtan Lévêque

Due to their particular optical and mechanical properties, plasmomechanical devices have become choice candidates in strain sensing applications. Using numerical simulation, a plasmomechanical system consisting of two gold nanoparticles with different shapes and separated by a small gap, deposited…

Time-resolved self-heating temperature measurements of AlInN/GaN HEMTs using CeO2 Raman micro-thermometers

R. Strenaer, Y. Guhel, C. Gaquiere, B. Boudart

The DC and RF electrical performance and reliability of GaN-based transistors depend on their thermal behavior. Therefore, measuring the self-heating temperature of these devices under real operating conditions with high accuracy is an important and challenging issue. For these reasons, we present…

Optimizing convolutional neural networks architecture using a modified particle swarm optimization for image classification

D. Elhani, A.C. Megherbi, A. Zitouni, F. Dornaika, S. Sbaa, Abdelmalik Taleb-Ahmed

Although Convolutional Neural Networks (CNNs) have been shown to be highly effective in image classificationtasks, designing their architecture to achieve optimal results is often challenging. This process is time consuming, requires significant effort and expertise, and is complicated by the large…

Fortran... ok, and what’s next?

Vincent Magnin, José Alves, Antoine Arnoud, Arjen Markus, Michele Esposito Marzino

Modern Fortran is a standardized language that includes object-oriented and parallel programming paradigms. The Fortran-lang community, created at the end of 2019, is actively working to modernize its ecosystem. New compilers are under development. And the fourth Fortran standard of the 21st…

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, Alexandra 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…
