Acousto-optic couplings in two-dimensional lithium niobate phoxonic crystal

Quentin Rolland, Samuel Dupont, Joseph Gazalet, Jean-Claude Kastelik

We investigate the acousto-optic couplings in two-dimensional infinite piezoelectric phoXonic crystal cavities. The periodic structure considered consists in a square array of air inclusions drilled in Lithium Niobate matrix. This structure allows the simultaneous confinement of acoustic and optic...

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...

Pulse compression waveforms design and Cross-ambiguity processing for Radar applications

Nadjah Touati, Charles Tatkeu, Atika Rivenq, Yassin El Hillali, Thierry Chonavel

Radar waveforms design is an important step to design a hole radar system. In this paper, several waveforms based on modified Costas codes are used. The properties and performances are tested and compared. We propose a detection based on cross-ambiguity calculation for these waveforms. Indeed, such...

Conception d'un réseau de capteurs acoustiques passifs pour un contrôle-santé intégré basse consommation et non-intrusif des structures aéronautiques et conduites de transport de fluides

Karl Hourany, Farouk Benmeddour, Emmanuel Moulin, Youssef Zaatar, Jamal Assaad

La corrélation d'un champ acoustique permet de caractériser un milieu de façon passive, cette étude a commencé à se développer depuis plusieurs années dans différentes applications de contrôle santé intégré (CSI). Une brève explication d'une étude faite précédemment pour la détection des...

A real-time terahertz beam monitoring application with a 1024-pixel CMOS terahertz camera module

Richard Al Hadi, Jean-Francois Lampin, Ullrich Pfeiffer

In this paper a terahertz beam monitoring application of an optically pumped molecular terahertz laser with a 1024-pixel CMOS terahertz camera is presented. The terahertz camera has been used to detect variations in real-time of the terahertz source beam around 2.52 THz.

Multi-phonon scattering processes in one-dimensional anharmonic biological superlattices : understanding the dissipation of mechanical waves in mineralized tissues

Pierre-Yves Guerder, Alix C. Deymier-Black, Nichlas Z. Swinteck, Jerome O. Vasseur, Olivier Bou Matar, Krishna Muralidharan, Pierre A. Deymier

The scattering of elastic waves in a one dimensional phononic (PnC) crystal composed of alternate collagen and hydroxy-apatite constituent layers is studied. These superlattices are metaphors for mineralized tissues present in bones and teeth. The collagen is treated as an open system elastic...

Synthesis and electrical characterisations of a low work function cesium oxide coating for high efficiency thermionic energy converter

François Morini, J.F. Robillard, Stéphane Monfray, I.D. Baikie, Thomas Skotnicki, Emmanuel Dubois

One main challenge associated with solid-state thermoelectric materials is to combine electron-crystal electrical conductivity and phonon-glass thermal properties that are difficult to conciliate. A markedly different principle of thermoelectric conversion is based on the micro-thermionic generator...

Effect of polarization switching cycles on the dielectric response and Rayleigh constant in Pb0.4Sr0.6TiO3 thin films

Kui Li, Xianlin Dong, Denis R Émiens, Tao Li, Ying Chen, Genshui Wang

Pb0.4Sr0.6TiO3 thin films with good fatigue endurance were crystallized at low temperature compatible with the current semiconductor technology. The effect of polarization switching cycles on the ferroelectric properties, dielectric response, and Rayleigh constant in thin films were systematically...
