Molecular beam epitaxial growth of multilayer 2D-boron nitride on Ni substrates from borazine and plasma-activated nitrogen

Jawad Hadid, Ivy Colambo, Jose Avila, Aexandre Plaud, Christophe Boyaval, D. Deresmes, Nicolas Nuns, Pavel Dudin, Annick Loiseau, Julien Barjon, Xavier Wallart, Dominique Vignaud

2D boron nitride (2D-BN) was synthesized by gas-source molecular beam epitaxy on polycrystalline and monocrystalline Ni substrates using gaseous borazine and active nitrogen generated by a remote plasma source. The excess of nitrogen atoms allows to overcome the thickness self-limitation active on...

THz photonics-based transmitter using multicore fiber combined with UTC-PD array for high data transmission in 300 GHz band

Bewindin Alfred Sawadogo, Aritrio Bandyopadhyay, Malek Zegaoui, Mohammed Zaknoune, Pascal Szriftgiser, Karen Baudelle, Monika Cieslikiewicz-Bouet, Géraud Bouwmans, Davy Gaillot, Esben Ravn Andresen, Guillaume Ducournau, Laurent Bigot

This work aims at illuminating an UTC-PD array with a multicore fiber towards multiple THz carrier generation. This photonics-based transmitter is expected to increase either the data rate via spatial multiplexing on different carriers or the emitted THz-power and therefore the transmission reach...

Photonics-Based Near-Field Measurement and Far-Field Characterization for 300-GHz Band Antenna Testing

Yusuke Tanaka, Guillaume Ducournau, Cybelle Belem-Goncalves, Frederic Gianesello, Cyril Luxey, Issei Watanabe, Akihiko Hirata, Norihiko Sekine, Akifumi Kasamatsu, Shintaro Hisatake

In this study, photonics-based near-field measurement and far-field characterization in a 300-GHz band are demonstrated using an electrooptic (EO) sensor with planar scanning. The field to be measured is up-converted to the optical domain (1550 nm) at the EO sensor and delivered to the measurement...

Système de vision neuro-inspirée : Application à la vision artificielle

Dimitri Henniquau, Pierre Falez, Philippe Devienne, Christel Vanbesien, Alexis Vlandas, A. Cappy, Virginie Hoel

L’architecture des systèmes numériques traditionnels est loin d’être optimale puisqu’un microprocesseur est tout autant une plaque chauffante qu’un calculateur (Intel Cooking [1]). Il devient donc urgent de proposer des architectures de traitement de l’information radicalement différentes, « neuro-...

Smart Full-Exploitation of Beamforming Fusion assisted Spectrum Sensing for Cognitive Radio

Sarra Ben Chaabane, Kais Bouallegue, Akram Belazi, Sofiane Kharbech, Ammar Bouallegue

This paper proposes blind spectrum sensing (SS) in a narrowband context called Beamforming Fusion assisted Spectrum Sensing (BFSS). Considering a channel with angles of arrival (AoA), we jointly exploit beamforming algorithms to make decisions about the detection of users on frequency resources....
