Giant rotary power of a fishnet-like metamaterial

S.X. Wang, F. Garet, Eric Lheurette, M. Astic, J.L. Coutaz, D. Lippens

We show experimentally and numerically that cholesteric-type metal-dielectric structures, made of twisted sub-wavelength hole elliptical–shaped arrays, exhibit strong optical activity and circular dichroism. The experimental demonstration is carried out with terahertz time-domain spectroscopy…

Stress-mediated magnetoelectric memory effect with uni-axial TbCo2/FeCo multilayer on 011-cut PMN-PT ferroelectric relaxor

Yannick Dusch, Nicolas Tiercelin, A. Klimov, S. Giordano, Vladimir Preobrazhensky, Philippe Pernod

We present here the implementation of a magnetoelectric memory with a voltage driven writing method using a ferroelectric relaxor substrate. The memory point consists of a magnetoelastic element in which two orthogonal stable magnetic states are defined by combining uni-axial anisotropy together…

Ultrafast short-range disordering of femtosecond-laser-heated warm dense aluminum

P. M. Leguay, A. Levy, B. Chimier, F. Deneuville, D. Descamps, C. Fourment, C. Goyon, S. Hulin, S. Petit, O. Peyrusse, J. J. Santos, P. Combis, B. Holst, V. Recoules, P. Renaudin, L. Videau, F. Dorchies

We have probed, with time-resolved x-ray absorption near-edge spectroscopy (XANES), a femtosecond-laser-heated aluminum foil with fluences up to 1 J/cm2. The spectra reveal a loss of the short-range order in a few picoseconds. This time scale is compared with the electron-ion equilibration time,…

Ultrafast optical technique for measuring the electrical dependence of the elasticity of piezoelectric thin film : demonstration on AlN

Arnaud Devos, P. Emery, E. Defay, N. Ben Hassine, G. Parat

We present a technique based on ultrafast acoustics which permits us to measure the electrical dependence of the elastic properties of a thin piezoelectric layer. Ultrafast acoustics offers a unique way of measuring elastic properties of thin-layer in a non-destructive way using ultrashort optical…

Si-nanorod-based plasmonic metamaterials : modeling and experiment

Silvia Peruch, Jean-Sébastien Bouillard, Daniel O'Connor, Wayne Dickson, Gregory Wurtz, Anatoli Zayats, Xiang-Lei Han, Tahsin Akalin, Guilhem Larrieu

Plasmonic metamaterials based on assemblies of metallic nanoparticles (MNPs) have finely tunable optical properties, which can be tailored for different applications, from sensing to waveguiding [1], [2]. Nanorods and nanorod arrays have been widely studied both theoretically and experimentally. In…
