La photonique dans la métropole lilloise

Laurent Bigot, Guillaume Ducournau, A. Amo

Ces dernières années, la métropole lilloise s’est imposée comme un pôle de recherche académique incontournable dans le domaine de la photonique. C’est notamment le cas des travaux en optique fibrée, en optique non-linéaire, en topologie ou encore en photonique-Terahertz, qui ont une forte…

How to tame a free non-laminar Savart sheet into individual jets?

Sofiene Oulded Taled Salah, Ghada Chouk, Alexis Duchesne, Nicolas de Cock, Khaoula Abrougui, Frédéric Lebeau, Stéphane Dorbolo

In this article, we study the division of a non-laminar Savart sheet into individual jets by mean of local disturbances. We paint a precise portrait of a free non-laminar Savart sheet formed by the vertical impact of a jet on a horizontal disk, its evolution in the air and its break up. We then…

Non-Hermitian skin effect in a phononic beam based on piezoelectric feedback control

Yabin Jin, Wenxin Zhong, Runcheng Cai, Xiaoying Zhuang, Yan Pennec, Bahram Djafari-Rouhani

Non-Hermitian systems have gained a great deal of interest in various wave problems due their ability of exhibiting unprecedented phenomena such as invisibility, cloaking, enhanced sensing, or the skin effect. The latter manifests itself by the localization of all bulk modes in a specific frequency…

Unstationary dynamics of drops subjected to MHz-surface acoustic waves modulated at low frequency

Philippe Brunet, Michael Baudoin

In the present work, we investigate the unstationary dynamics of sessile droplets subjected to high-frequency surface acoustic waves modulated at a lower frequency close to the first inertio-capillary resonance mode of the drop. Under the action of both acoustic streaming and radiation pressure,…

High Breakdown Field and Low Trapping Effects up to 1400 V in Normally Off GaN‐on‐Silicon Heterostructures

Idriss Abid, Youssef Hamdaoui, Jash Mehta, F Medjdoub

In this study, we report on the development of a fully normally-off high electron mobility transistor (HEMT) gallium nitride on silicon (GaN-on-Si) heterostructures designed for high voltage operation. The normally-off configuration was achieved by means of a p-gallium nitride (p-GaN) cap layer…

CRC-Based Correction of Multiple Errors Using an Optimized Lookup Table

Vivien Boussard, Stephane Coulombe, François-Xavier Coudoux, Patrick Corlay

In this paper, we propose a new approach to perform multiple error correction in wireless communications over error-prone networks. It is based on the cyclic redundancy check syndrome, using an optimized lookup table that avoids performing arithmetic operations. This method is able to achieve the…

Molecular beam epitaxial growth of 2D-boron nitride on Ni substrates

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 Ni substrates using gaseous borazine and active nitrogen generated by a remote plasma source. Based on spatially resolved photoemission spectroscopy and on the detection of the π plasmon peak, we discuss the origin of…

De la théorie à la pratique dans l’enseignement du traitement du signal : initiation à la recherche

Lynda Chehami, Nikolay Smagin, Jamal Assaad, Pierre Campistron, Frédéric Jenot, Emmanuel Moulin

Le débat entre la théorie et la pratique dans l'enseignement sur l'importance de chacun comme base de la formation en Master existe depuis plusieurs années. Ce lien est souvent sous-évaluée et on a tendance à oublier que de la théorie naît la pratique et que la pratique est basée sur la…

Unidirectional Coherent Phonon Emission in an Optomechanic Nanobeam Containing Coupled Cavities

Alexander Korovin, Yan Pennec, Bahram Djafari-Rouhani

Nonreciprocal phonon emission is predicted theoretically from the coherent excitation of two coupled optomechanical cavities arranged along a phoxonic crystal nanobeam. The latter consists of a periodic array of holes and stubs and exhibits simultaneous photonic and phononic bandgaps. It is shown…
