Phase-control in two-dimensional phononic crystals

N. Swinteck, S. Bringuier, J.F. Robillard, Jerome O. Vasseur, Anne-Christine Hladky, K. Runge, P.A. Deymier

A theoretical model is developed to ascertain the necessary band structure and equi-frequency contour (EFC) features of two-dimensional phononic crystals (PCs) for the realization of phase control between propagating acoustic waves. Two different PCs, a square array of cylindrical polyvinylchloride...

Anisotropic excitonic effects in the energy loss function of hexagonal boron nitride

S. Galambosi, L. Wirtz, J.A. Soininen, J. Serrano, A. Marini, K. Watanabe, T. Taniguchi, S. Huotari, A. Rubio, K. Hamalainen

The anisotropy of the valence energy-loss function of hexagonal boron nitride (hBN) is shown to be largely enhanced by the highly inhomogeneous character of the excitonic states. The energy loss with momentum transfer parallel to the BN layers is dominated by strongly bound, quasi-two-dimensional...

Subterahertz hypersound attenuation in silica glass studied via picosecond acoustics

Simon Ayrinhac, Marie Foret, Arnaud Devos, Benoit Ruffle, Eric Courtens, René Vacher

We report picosecond acoustic measurements in silica-glass films grown by wet thermal oxidation on a (111) silicon substrate. The longitudinal acoustic phonons are observed over the range from 150 to 300 GHz using an infrared pump and a second harmonic blue probe. The transducer is an aluminum thin...

Vortex state in thin films of multicomponent ferroelectrics

Laurent Baudry, Anaïs Sené, Igor A. Luk'Yanchuk, Laurent Lahoche

The distribution of polarization in thin film of multicomponent weak anisotropic ferroelectric under application of an axially symmetric electric field induced by circular electrodes is studied. We demonstrate that above a certain critical field the instability towards abrupt formation of...

Co-integrated microfluidic and THz functions for biochip devices

Simon Laurette, A. Treizebre, Bertrand Bocquet

TeraHertz (THz) spectroscopy is becoming an alternative way to probe biological interactions in real-time conditions. However, accurate and reproducible THz measurements of aqueous solutions, largely represented in life sciences, remain difficult. A THz microsystem which couples both...

Highly coherent terahertz wave generation with a dual-frequency Brillouin fiber laser and a 1.55 μm photomixer

Guillaume Ducournau, P. Szriftgiser, Tahsin Akalin, Alexandre Beck, Denis Bacquet, Emilien Peytavit, Jean-Francois Lampin

Thanks to a portable dual-frequency Brillouin fiber laser and a 1.55 μm photomixer, we report the generation of a highly coherent kilohertz level submillimeter wave emission. Low-cost telecommunications components are used to achieve very simple source architecture. The photomixer is composed of a...
