Photonics-enabled 1.04-Tbit/s Aggregated Data-rate in the 600-GHz-band

Guillaume Ducournau, Pascal Szriftgiser, Yuma Kawamoto, Weijie Gao, Abdu Subahan Mohammed, Malek Zegaoui, Mohammed Zaknoune, Tadao Nagatsuma

We demonstrate in this work the use of a waveguide-integrated THz photodiode in the 600 GHz band, combined with a waveguide-based receiver. Leveraging on the wide available bandwidth of this association, beyond 1 terabit per second aggregated data-rate is reached with a bit-error-rate performance...

Atomistic insights into the nucleation and growth of hexagonal boron nitride and graphene heterostructures

Mohamed Achehboune, Kazem Zhour, Jaroslaw Dabrowski, Dominique Vignaud, Max Franck, Mindaugas Lukosius, Jean-François Colomer, Luc Henrard

Graphene and hexagonal boron nitride (hBN) are two-dimensional (2D) materials with a similar atomic structure but drastically different although complementary electronic properties. The large-scale synthesis of h-BN/graphene heterostructures with high crystallographic quality is required to fully...

Experimental closed-loop flow separation control: Data- and phenomenological-driven approaches

T. Arnoult, G. Acher, V. Nowinski, P. Vuillemin, C. Briat, P. Pernod, C. Ghouila-Houri, A. Talbi, E. Garnier, C. Poussot-Vassal

Flow control aims at modifying a natural flow state to reach an other flow state considered as advantageous. In this paper, active feedback flow separation control is investigated with two different closed-loop control strategies, involving a reference signal tracking architecture. Firstly, a data-...

On the reduction of gas permeation through the glass windows of micromachined vapor cells using Al₂O₃ coatings

C. Carlé, A. Mursa, P. Karvinen, S. Keshavarzi, M. Abdel Hafiz, V. Maurice, R. Boudot, N. Passilly

Stability and precision of atomic devices are closely tied to the quality and stability of the internal atmosphere of the atomic vapor cells on which they rely. Such an atmosphere can be stabilized by building the cell with low permeation materials such as sapphire or aluminosilicate glass in...

Terahertz molecular water laser using quantum cascade laser pumping

L. Juppet, Alexandra Khabbaz, J. Lampin, O. Pirali

Molecular lasers pumped by quantum cascade laser (QCL) open new possibilities for THz generation and its numerous applications, in particular, for high resolution molecular spectroscopy. In this article, a THz water laser pumped by a mid-infrared QCL was demonstrated using the broad tunability of...

Surface acoustic wave confinement inside uncorrelated distributions of subwavelength scatterers

Thibault Deletang, Adnane Noual, Bernard Bonello, Roman Buisine, Yan Pennec, Bahram Djafari-Rouhani

We report an experimental study of surface acoustic wave (SAW) localization and propagation in random metasurfaces composed of Al scatters using pump–probe spectroscopy. Thanks to this technique, wideband high frequency acoustic modes are generated, and their dynamical propagation directly from...

Demonstration of avalanche capability in 800 V vertical GaN-on-Silicon diodes

Youssef Hamdaoui, Idriss Abid, Sondre Michler, Katir Ziouche, F Medjdoub

High-quality pseudo-vertical p-n diodes using a GaN-on-silicon heterostructure are reported. An optimized fabrication process including a beveled deep mesa as edge termination and reduced ohmic contact resistances enabled high on-state current density and low onresistance. A uniform breakdown...
