Nanomechanical modulation cavities of localized surface plasmon resonance with elastic whispering-gallery modes

Z. Oumekloul, M. Moutaouekkil, Gaëtan Lévêque, Abdelkrim Talbi, A. Mir, Abdellatif Akjouj

he dispersion of mechanical vibration limits nano-optomechanical modulation. In this work, we propose an optomechanical modulation exploiting elastic local resonances, also called whispering-gallery modes (WGMs). We find that our structure supports two quadripolar and two hexapolar elastic WGMs,…

High speed mid-IR quantum cascade detector at room temperature

G. Quinchard, C. Mismer, V. Trinite, A. Evirgen, A. Larrue, M. Hakl, Jean-Francois Lampin, Emilien Peytavit, S Barbieri, A. Delga

We present a high-speed antenna enhanced Quantum Cascade Detector at 10.3μm. By using a coherent detection scheme and thin InGaAs/AlInAs heterostructure embedded in metal-metal patch antenna, we demonstrate a heterodyne response up to 67 GHz at room temperature.

Low-Temperature-Grown Gallium Arsenide Photoconductors with Photoresponse Reaching 25 mA/W under 1550nm Cw Excitation

Charbel Tannoury, Maximilien Billet, Christophe Coinon, Jean-Francois Lampin, Emilien Peytavit

We show in this communication that photoconductors based on GaAs grown at low temperature can exhibit photoresponses as high as 25 mA/W under continuous-wave 1550-nm-wavelength illumination. It is achieved by using an optical Fabry-Pérot cavity in order to improve the external quantum efficiency…

Inducing dispersion curves with negative group velocity in inertially amplified phononic crystals through the application of an external state of prestress

M. Miniaci, M. Mazzotti, A. Amendola, F. Fraternali

In this paper, we report about the effect of the application of a state of prestress on the band structure of a periodic phononic crystal characterized by an inertial amplification mechanism. Through a numerical example, we show the possibility of inducing negative group velocity in an isolated…

Physicochemical characterizati on of the fuel by the ultrasound method

Said Soudani, Mohammed Mekkaoui, Georges Nassar, Ziane Derouiche

A physical medium, whatever its nature ,solid, liquid or gaseous is characterized by physicochemical parameter which are unique to it and which differentiate it from any other medium. But it can also be characterized and differentiated by its acoustic parameters: it’s like two sides of the same…
