Métasurfaces absorbantes flexibles en ondes millimétriques

Ludovic Burgnies, Jianping Hao, Colin Mismer, Guillaume Ducournau, Eric Lheurette, Didier Lippens

Dans cette communication, nous présentons une étude de faisabilité ainsi que la vérification expérimentale de structures planaires absorbantes dans la gamme des ondes millimétriques réalisées en technologie flexible. L'absorption large bande est obtenue grâce aux différentes fréquences de…

200 GHz coherent wireless link using photonics-based emission

Guillaume Ducournau, Y. Yoshimizu, S. Hisatake, F. Pavanello, Emilien Peytavit, Mohammed Zaknoune, T. Nagatsuma, Jean-Francois Lampin

We investigated a coherent THz link at 200 GHz, with variable data rate up to 11 Gbit/s, featuring the combination of a quasi-optic UTC-PD emitter and a high sensitivity electronic receiver. This coherent link relies on an optical frequency comb generator at emission to produce an optical beat note…

Improved efficiency by the effect of strain on the structure of a solar cell based on GaInP/GaAs

Abdelkader Aissat, Rachid Bestam, Jean-Pierre Vilcot

This work is aimed at the study of GaInP-based photovoltaic cell. The effects of In content, lattice parameter mismatch and thickness of the SiO2 insulating layer on the characteristics and efficiency of the GaInP structure were investigated. We noticed that for higher In concentrations, the band…

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…

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.
