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...

Millimeter-Wave Phased Arrays and Over-the-Air Characterization for 5G and Beyond

Mattia Maggi, Syrine Hidri, Loic Marnat, Mauro Ettorre, Gerardo Orozco, Marc Margalef-Rovira, Christophe Gaquière, Kamel Haddadi

Millimeter-wave (mm-wave) technology is a viable candidate to address the growing data traffic in 5G wireless communication and beyond. However, challenges related to free-space propagation loss, atmospheric absorption, scattering, and nonline-of-sight propagation must be addressed to benefit from...

Elucidating the oscillation instability of sessile drops triggered by surface acoustic waves

Nicolas Chastrette, Michael Baudoin, Philippe Brunet, Laurent Royon, Régis Wunenburger

The oscillation instability of sessile drops is ubiquitous in surface acoustic wave (SAW) -powered digital microfluidics. Yet the physics underlying these phenomena has not been elucidated owing to the complex interplay between hydrodynamics, acoustics, and capillarity. We decipher the instability...

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-...

Equal-efficiency diffraction of unpolarized wideband light with acousto-optic filters

Samuel Dupont, Justine Champagne, Jean-Claude Kastelik

We present the diffraction of unpolarized light over a broad wavelength range using paratellurite Acousto-Optic Tuneable Filters. The diffraction of unpolarized light usually relies on a specific operating point that is sensitive to the wavelength and angle of incidence, resulting in an operating...

Temperature and Gate-Length Dependence of Subthreshold RF Detection in GaN HEMTs

Gaudencio Paz-Martínez, Ignacio Íñiguez-De-La-Torre, Héctor Sánchez-Martín, José Antonio Novoa-López, Virginie Hoel, Yvon Cordier, Javier Mateos, Tomás González

The responsivity of AlGaN/GaN high-electron mobility transistors (HEMTs) when operating as zero-bias RF detectors in the subthreshold regime exhibits different behaviors depending on the operating temperature and gate length of the transistors. We have characterized in temperature (8–400 K) the...

Map-Matching-Based Localization Using Camera and Low-Cost GPS For Lane-Level Accuracy

Rahmad Sadli, Mohamed Afkir, Abdenour Hadid, Atika Rivenq, Abdelmalik Taleb-Ahmed

For self-driving systems or autonomous vehicles (AVs), accurate lane-level localization is a necessity for performing complex driving maneuvers. Classical GNSS based methods are usually not accurate enough to have lane-level localization to support the AV’s maneuvers. LiDAR-based localization can...

Efficient palmprint biometric identification systems using deep learning and feature selection methods

Selma Trabelsi, Djamel Samai, Fadi Dornaika, Azeddine Benlamoudi, Khaled Bensid, Abdelmalik Taleb-Ahmed

Over the past two decades, several studies have paid great attention to biometric palmprint recognition. Recently, most methods in literature adopted deep learning due to their high recognition accuracy and the capability to adapt with different acquisition palmprint images. However, high-...
