Guided acoustic wave resonators using an acoustic Bragg mirror

I. Kone, F. Domingue, H. Jacquinot, M. Borel, M. Gorisse, A. Reinhardt, G. Parat, F. Casset, D. Pelissier-Tanon, J.F. Carpentier, L. Buchaillot, Bertrand Dubus

Lamb wave devices have recently gained an interest for providing narrow bandpass filters in wireless transmission systems. Their cointegration with film bulk acoustic wave resonators is a major advantage, enabling the possibility to provide simultaneously several radio frequency and intermediate-…

Interface engineering for improved light transmittance through photonic crystal flat lenses

Geoffroy Scherrer, Maxence Hofman, Wojciech Smigaj, B. Gralak, X. Melique, O. Vanbesien, D. Lippens, Colette Dumas, Benoît Cluzel, F. de Fornel

In this paper, we present photonic crystal flat lenses with interfaces engineered to improve the light transmittance thanks to a broad angles impedance matching. The interface engineering consists in the realization of antireflection gratings on the edges of the lenses which are designed to reduce…

Negative refraction of surface acoustic waves in the subgigahertz range

Bernard Bonello, Laurent Belliard, Juliette Pierre, Jerome O. Vasseur, Bernard Perrin, Olga Boyko-Kazymyrenko

We used the picosecond ultrasonic technique to experimentally demonstrate the negative refraction of surface acoustic waves in a two-dimensional phononic crystal. The sample is made of a square lattice of circular voids drilled at the surface of a thick silica substrate. The lattice parameter is of…

Sub-terahertz resistive mixing in a AlGaN/GaN HEMT

Kamel Madjour, Guillaume Ducournau, Sylvie Lepilliet, Tahsin Akalin, Jean-Francois Lampin, Marie-Antoinette Di Forte-Poisson, Sylvain Laurent Delage, Christophe Gaquière

An AlGaN/GaN based field effect transistor (FET) has been designed, fabricated, and used as a resistive mixer for heterodyne detection in the 140-220 GHz frequency range. A double VNA heterodyne measurement setup has been used in an on-wafer configuration to accurately quantify the incident…
