Ultrawide-bandwidth single-channel 0.4-THz wireless link combining broadband quasi-optic photomixer and coherent detection

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

Free space communications with huge data capacity have become a key point for the development of mobile access, services, and network technologies convergence. Wireless links using emerging terahertz technologies, also referred to as T-ray communications, have become an intensive research field…

Narrow linewidth tunable terahertz radiation by photomixing without servo-locking

Antoine Rolland, Guillaume Ducournau, Gwennaël Danion, Goulc'Hen Loas, Marc Brunel, Alexandre Beck, Fabio Pavanello, Emilien Peytavit, Tashin Akalin, Mohammed Zaknoune, Jean-Francois Lampin, François Bondu, Marc Vallet, Pascal Szriftgiser, Denis Bacquet, Mehdi Alouini

A beatnote, tunable from dc to 1 THz, provided by a dual-frequency laser is used to feed an unitravelling carrier photodiode in order to produce a highly coherent THz signal radiated by a transverse-electromagnetic-horn antenna. The THz signal is detected and analyzed by a subharmonic mixer coupled…

Theoretical and experimental investigation of Lamb waves characteristics in AlN/TiN and AlN/TiN/NCD composite membranes

Ali Soltani, Abdelkrim Talbi, J-C Gerbedoen, Jean-Claude de Jaeger, Philippe Pernod, V. Mortet, A. Bassam

In this study, we present a theoretical and experimental investigations of the zero order quasi-symmetric (S0) Lamb waves mode propagating in AlN/TiN and AlN/TiN/NCD composite membranes. Theoretical analysis of S0 mode characteristics shows that The AlN/TiN membrane enables to achieve smooth…

Electronic and physico-chemical properties of nanometric boron delta-doped diamond structures

Gauthier Chicot, Alexandre Fiori, P.N. Volpe, Thu Nhi Tran Thi, Jean-Claude Gerbedoen, Jessica Bousquet, M.P. Alegre, J.C. Pinero, D. Araujo, F. Jomard, Ali Soltani, Jean-Claude de Jaeger, J. Morse, J. Härtwig, Nicolas Tranchant, C. Mer-Calfati, Jean-Charles Arnault, Julien Delahaye, Thierry Grenet, David Eon, Franck Omnès, Julien Pernot, Etienne Bustarret

Heavily boron doped diamond epilayers with thicknesses ranging from 40 to less than 2 nm and buried between nominally undoped thicker layers have been grown in two different reactors. Two types of [100]-oriented single crystal diamond substrates were used after being characterized by X-ray white…

Silicon nanotweezers inside liquid for the real time characterization of DNA degradation under radiotherapy treatment

Grégoire Perret, T. Lacornerie, V. Kumemura, N. Lafitte, H. Guillou, L. Jalabert, E. Lartigau, T. Fujii, Fabrizio Cleri, H. Fujita, Dominique Collard

Tumor cell killing by γ-ray beams in radiotherapy is currently based on a rather empirical understanding of the basic mechanisms and effectiveness of DNA damage by radiation. On the other hand, the mechanical behavior of DNA, e.g., sequence-sensitivity, elastic vs. plastic response, is well…

Control of the ionization state of three single donor atoms in silicon

B. Voisin, M. Cobian, X. Jehl, M. Vinet, Yann-Michel Niquet, Christophe Delerue, Silvano de Franceschi, M. Sanquer

By varying the front-gate and the substrate voltages in a short silicon-on-insulator trigate field-effect transistor, we control the ionization state of three arsenic donors. We obtain good quantitative agreement between three-dimensional electrostatic simulations and experiment for the control…
