200 GHz coherent wireless link using photonics-based emission

Guillaume Ducournau, Y. Yoshimizu, S. Hisatake, F. Pavanello, Emilien Peytavit, Mohammed Zaknoune, T. Nagatsuma, Jean-Francois Lampin

We investigated a coherent THz link at 200 GHz, with variable data rate up to 11 Gbit/s, featuring the combination of a quasi-optic UTC-PD emitter and a high sensitivity electronic receiver. This coherent link relies on an optical frequency comb generator at emission to produce an optical beat note…

Extension of the crosstalk cancellation method in ultrasonic transducer arrays from the harmonic regime to the transient one

Abdelmajid Bybi, Sébastien Grondel, Jamal Assaad, Anne-Christine Hladky

This paper describes a procedure to extend the crosstalk correction method presented in a previous paper [A. Bybi, S. Grondel, J. Assaad, A.–C. Hladky-Hennion, M. Rguiti, Reducing crosstalk in array structures by controlling the excitation voltage of individual elements: a feasibility study,…

Terahertz time-domain spectroscopy of absorbing materials and of metamaterials

Jean-Louis Coutaz, M. Bernier, Frédéric Garet, S. Joly, Y. Miyake, H. Minamide, Eric Lheurette, Didier Lippens

This paper gives a review of recent works we performed in view of characterizing natural materials and metamaterials by terahertz time-domain spectroscopy. We address materials that exhibit a low transmittance in given narrow spectral bands or over the whole experimental spectral window. We give…

Hybrid organic-inorganic nanocomposites for terahertz applications

D. Hourlier-Bahloul, Srisaran Venkatachalam, Christophe Boyaval, Guillaume Ducournau, Y. Blum, Jean-Francois Lampin

The TeraHertz (THz) portion corresponds to the part of the electromagnetic spectrum having frequencies ranging from 0.3 to 10 THz. Unlike UV or X-rays, THz photons are not energetic enough to break chemical bonds or to ionize atoms or molecules. These radiations have found widespread applications…

Elastic field scattered by a resonator in an acoustic metamaterial

Bernard Bonello, Rémi Marchal, Rayisa P. Moiseyenko, Yan Pennec, Bahram Djafari-Rouhani, J. Zhao, Olga Boyko-Kazymyrenko

Locally resonant sonic materials are artificially structured composites designed to exhibit negative effective mass density and/or elastic constants at frequencies below the Bragg band gap, giving rise to one or several forbidden bands in a frequency range where the elastic wavelength is much…

Scanning tunneling microscopy of GaAs/GaAsSb nanowires

Adrian Díaz Álvarez, Pierre Capiod, Maxime Berthe, Tao Xu, Jean-Philippe Nys, Isabelle Lefebvre, Philippe Caroff, Philipp Ebert, B. Grandidier

Understanding surface structure and surface composition is of particular importance for semiconductor nanowire applications, since they might strongly contribute to the electrical, optical and thermal properties of the Nanowires. A prototypical material is GaAs, where polytype inclusions consisting…

Acousto-optic couplings in two-dimensional lithium niobate phoxonic crystal

Quentin Rolland, Samuel Dupont, Joseph Gazalet, Jean-Claude Kastelik

We investigate the acousto-optic couplings in two-dimensional infinite piezoelectric phoXonic crystal cavities. The periodic structure considered consists in a square array of air inclusions drilled in Lithium Niobate matrix. This structure allows the simultaneous confinement of acoustic and optic…

Step-conformal deposition of TiO2 and MnO2 electrodes on advanced silicon microstructures for 3D Li-ion microbatteries and micro-supercapacitors

Étienne Eustache, Camille Douard, Pascal Tilmant, Laurence Morgenroth, Pascal Roussel, Thierry Brousse, Christophe Lethien

To get autonomous smart microsystem, a miniaturized power source should be integrated. As the device is surface limited, the energy and power performances of commercially available planar microbatteries and micro-supercapacitors are not sufficient to reach this goal. To improve their performances…

Deformation of droplets with magnetic nanoparticles in a rotating magnetic field

Sergey S. Koshelyuk, Yu V. Pylnov, Vladimir L. Preobrazhensky, Philippe Pernod

This paper investigates the change in contact angle of droplets of fluid containing dispersed nanoparticles (nanofluid) stabilized in oleic acid and ethanol placed in a rotating magnetic field. Paramagnetic nanoparticles with an average size 100 nm were injected into the droplets and situated on…
