Test de susceptibilité de communication LTE face aux interférences produites par le contact caténaire-pantographe

Olivier Stienne, Virginie Deniau, Eric Pierre Simon, Mohamed Raouf Kousri

Les transports ferroviaires doivent continuellement évoluer pour conserver une bonne attractivité. En particulier, les services offerts à bord des trains doivent apporter un bon niveau de confort aux passagers. Dans ce contexte, les opérateurs veulent permettre un accès à internet de qualité à bord…

Addressing the exciton fine structure in colloidal nanocrystals: the case of CdSe nanoplatelets

Elena V Shornikova, Louis Biadala, Dmitri R Yakovlev, Victor F Sapega, Yuri G Kusrayev, Anatolie Mitioglu, Mariana V Ballottin, Peter C M Christianen, Vasilii V Belykh, Mikhail V Kochiev, Nikolai N Sibeldin, Aleksandr A Golovatenko, Anna V Rodina, Nikolay A Gippius, Alexis Kuntzmann, Ye Jiang, Michel Nasilowski, Benoit Dubertret, Manfred Bayer

We study the band-edge exciton fine structure and in particular its bright-dark splitting in colloidal semiconductor nanocrystals by four different optical methods based on fluorescence line narrowing and time-resolved measurements at various temperatures down to 2 K. We demonstrate that all these…

Toward a better understanding of the doping mechanism involved in Mo(tfd-COCF3)(3) doped PBDTTT-c

J. Euvrard, A. Revaux, S. S. Nobre, A. Kahn, Dominique Vuillaume

In this study, we aim to improve our understanding of the doping mechanism involved in the polymer poly[(4,8-bis-(2-ethylhexyloxy)-benzo(1,2-b:4,5-b')dithiophene)-2,6-diyl-alt-(4-(2-ethylhexanoyl)-thieno[3,4-b]thiophene-)-2-6-diyl)] (PBDTTT-c) doped with tris[1-(trifluoroethanoyl)-2-(…

Voltage controlled sub-THz detection with gated planar asymmetric nanochannels

H. Sanchez-Martin, J. Mateos, J. A. Novoa, J. A. Delgado-Notario, Y. M. Meziani, S. Perez, H. Theveneau, Guillaume Ducournau, Christophe Gaquière, T. Gonzalez, I. Iniguez-De-La-Torre

This letter reports on room temperature sub-THz detection using self-switching diodes based on an AlGaN/GaN heterostructure on a Si substrate. By means of free-space measurements at 300 GHz, we demonstrate that the responsivity and noise equivalent power (NEP) of sub-THz detectors based on planar…

Ferroelastic relaxation at 20 GHz evidenced by large frequency range picosecond acoustics

Arnaud Devos, F. Casset, G. Le Rhun, P. Emery, S. Fanget, E. Defay

We present a method to perform elastic measurements on a thin-film as a function of frequency between a few GHz and a few hundred GHz. The technique is mainly based on Picosecond Acoustics (PA), which is an ultrafast optical technique that realizes pulse-echo measurements in the hypersonic range.…

Indoor 100 Gbit/s THz data link in the 300 GHz band using fast photodiodes

Vinay Kumar Chinni, Malek Zegaoui, Christophe Coinon, X. Wallart, Emilien Peytavit, Jean-Francois Lampin, P. Szriftgiser, Mohammed Zaknoune, Guillaume Ducournau

This paper presents recent achievements towards 100 Gbit/s data links for future 300 GHz communication systems with the new IEEE 802.15.3d standard. Resonant photodiodes structures, and their application for QAM-16 data links in the THz range are shown in indoor scenario.

Zipping-Depinning: Dissolution of Droplets on Micropatterned Concentric Rings

José Encarnación Escobar, Erik Dietrich, S. Arscott, Harold J. W. Zandvliet, Xuehua Zhang, Detlef Lohse

The control of the surface wettability is of great interest for technological applications as well as for the fundamental understanding of surface phenomena. In this article, we describe the dissolution behavior of droplets wetting a micropatterned surface consisting of smooth concentric circular…

Influence of capillarity and gravity on confined Faraday waves

S. Diwakar, Vibhor Jajoo, Sakir Amiroudine, Satoshi Matsumoto, Ranga Narayanan, Farzam Zoueshtiagh

Experiments characterizing the influence of gravity and interfacial tension on Faraday instability in immiscible, confined fluid layers are presented. The variation in interfacial tension was obtained by controlling the temperature of a suitable binary fluid pair while the influence of gravity was…

Compact Waveguide and Guided Beam Pattern Based on the Whispering-Gallery Mode of a Hollow Pillar in a Phononic Crystal Plate

Weitao Yuan, Jinfeng Zhao, Bernard Bonello, Bahram Djafari-Rouhani, Xiaoqing Zhang, Yongdong Pan, Zheng Zhong

We report on the experimental evidence of the guiding of the lowest order antisymmetric Lamb mode (A0) through a compact waveguide consisting of aligned hollow pillars in between a square-latticed array of solid pillars on a thin slab. We analyze both numerically and experimentally the guiding…

Propagation of elastic waves in a one-dimensional high aspect ratio nanoridge phononic crystal phononic crystal

Abdellatif Gueddida, Yan Pennec, El Houssaine El Boudouti, George Fytas, Bahram Djafari-Rouhani

We investigate the propagation of elastic waves in a one-dimensional (1D) phononic crystal constituted by high aspect ratio epoxy nanoridges that have been deposited at the surface of a glass substrate. With the help of the finite element method (FEM), we calculate the dispersion curves of the…
