Thermal characterization using optical methods of AlGaN/GaN HEMTs on SiC substrate in RF operating conditions

Leny Baczkowski, Jean-Claude Jacquet, Olivier Jardel, Christophe Gaquière, myriam moreau, Dominique Carisetti, Laurent Brunel, Franck Vouzelaud, Yves Mancuso

Performance and reliability of wide bandgap high-power amplifiers are correlated with their thermal behavior. Thermal model development and suitable temperature measurement systems are necessary to quantify the channel temperature of devices in real operating conditions. As a direct temperature…

Reaching the quantum limit of sensitivity in electron spin resonance

A Bienfait, Y Kubo, M Stern, Xin Zhou, T Schenkel, D Vion, D Esteve, B Julsgaard, K Mølmer, P. Bertet, J;j. Pla, C.C. Lo, J.J.L. Morton

The detection and characterization of paramagnetic species by electron spin resonance (ESR) spectroscopy is widely used throughout chemistry, biology and materials science 1 , from in vivo imaging 2 to distance measurements in spin-labelled proteins 3. ESR relies on the inductive detection of…

Numerical simulation of the transient ultrasonic wave reflection at a liquid-solid interface

Nadir Maghlaoui, Hakim Djelouah, Mohamed Ourak, Djema Belgroune

In the nondestructive evaluation domain, the reflection of ultrasonic waves at liquid-solid interfaces generates interesting and useful phenomena when the incident angle approaches the longitudinal critical angle or Rayleigh angle. In this paper, we have developed a model for the study of the…

Acousto-Optical Tunable Transmissive Grating Beam Splitter

Anthony Dieulangard, Jean-Claude Kastelik, Samuel Dupont, Joseph Gazalet

We present a tunable transmissive grating beam splitter for multiple laser line separation based on acousto-optic interaction in tellurium dioxide. Acousto-optic devices are well known for light modulation, frequency shifting, filtration or deflection. For a deflector, the incident light beam is…

Bulk elastic waves with unidirectional backscattering-immune topological states in a time-dependent superlattice

N. Swinteck, S. Matsuo, K. Runge, Jerome O. Vasseur, P. Lucas, P. Deymier

Recent progress in electronic and electromagnetic topological insulators has led to the demonstration of one way propagation of electron and photon edge states and the possibility of immunity to backscattering by edge defects. Unfortunately, such topologically protected propagation of waves in the…

A planar micro thermoelectric generator with high thermal resistance

Zheng Yuan, Katir Ziouche, Zahia Bougrioua, Pascale Lejeune, Tuami Lasri, Didier Leclercq

This paper presents the modelling, design, fabrication and characterization of a planar micro thermoelectric generator (μTEG) which is able to convert waste heat into a few microwatts of electrical power. In order to get a better performance under a large variety of heat sources even if their…

Toward quantitative modeling of silicon phononic thermocrystals

V. Lacatena, M. Haras, J.F. Robillard, S. Monfray, T. Skotnicki, Emmanuel Dubois

The wealth of technological patterning technologies of deca-nanometer resolution brings opportunities to artificially modulate thermal transport properties. A promising example is given by the recent concepts of "thermocrystals" or "nanophononic crystals" that introduce regular…

Multiport Reflectometer Based on Subtractive Mixing

Abdelhatif El Fellahi, Kamel Haddadi, David Glay, Tuami Lasri

A compact multiport reflectometer using a new subtractive mixing scheme for the determination of reflection coefficients in the frequency range of 1-10 GHz is proposed. Compared with classical multiport reflectometers, the architecture proposed reduces the design complexity. Comparison between…
