Narrow linewidth tunable THz signal radiated by 1.55 µm photomixing

Alain Rolland, Guillaume Ducournau, Goulc'Hen Loas, Alexandre Beck, Fabio Pavanello, Emilien Peytavit, Tahsin Akalin, Mohammed Zaknoune, Jean-Francois Lampin, Marc Brunel, François Bondu, Marc Vallet, Mehdi Alouini

THz has become a wide field of investigation opening new opportunities in a growing number of domains of physics, chemistry, and biology. Among the different techniques existing today to generate THz fields, heterodyning two optical frequencies is a useful approach when tunability is required.…

Indoor radio channel characterization at 60 GHz

Maríateresa Martínez Inglés, Juan Pascual García, José Víctor Rodríguez, José María Molina García-Pardo, Leandro Juan Llácer, Davy Gaillot, M. Lienard, Pierre Degauque

This TD presents a set of 10x10 MIMO measurements at 60GHz in an indoor environment. A theoretical and experimental analysis has been done by means of a 3D ray tracing tool and the high resolution parameter estimator RiMAX. Results show the complexity of modeling the radio channel at the mmW…

Investigation of optical and chemical bond properties of hydrogenated amorphous silicon nitride for optoelectronics applications

Etienne Herth, H Desré, Emmanuelle Algré, Christiane I. Legrand, Tuami Lasri

The aim of this work is to determine optimal deposition parameters of silicon nitride for optical applications. The authors present the investigation of hydrogenated amorphous silicon nitride SiNx:H deposited by the low temperature PECVD method in high frequency reactors. The study of hydrogen…

A study on millimetre-wave tunable bandpass filter based on polymer cap deflection

S. Seok, J.G. Kim, N. Rolland, P.A. Rolland

This paper presents a new tuning mechanism for millimetre-wave BPF based on deflection of the BCB membrane of BCB packaging cap. A 3-pole parallel-coupled microstrip filter operating at 60 GHz is first implemented on 30 µm-thick BCB polymer substrate and then BCB-capped through our new anti-…

Experimental evidence of zero-angle refraction and acoustic wave-phase control in a two-dimensional solid/solid phononic crystal

Jerome O. Vasseur, B. Morvan, A. Tinel, N. Swinteck, Anne-Christine Hladky, P.A. Deymier

The square symmetry of the equifrequency contour of longitudinal waves in a solid/solid two-dimensional phononic crystal (PC) is shown through numerical calculations and experiments to lead to peculiar propagation phenomena. A slab of steel/epoxy PC immersed in water refracts incident longitudinal…

Tight-binding calculations of the optical properties of HgTe nanocrystals

Guy Allan, Christophe Delerue

We propose a tight-binding model of HgTe which gives an accurate band structure in a wide energy range compared to recent ab initio calculations. The inverted band structure near the Fermi level and its temperature dependence are also very well described. Using this parametrization, we study the…
