Single channel 100 Gbit/s link in the 300 GHz band

Vinay Kumar Chinni, Philipp Latzel, Malek Zegaoui, Christophe Coinon, X. Wallart, Emilien Peytavit, Jean-Francois Lampin, Klaus Engenhardt, P. Szriftgiser, Mohammed Zaknoune, Guillaume Ducournau

We report on the achievement of single channel 100 Gbit/s transmission, using linear resonant cavity enhanced unitravelling carrier photodiodes and QAM-16 modulation format. The indoor wireless link has been validated for up to 100 Gbit/s and 280 GHz carrier frequency.

High-resolution THz gain measurements in optically pumped ammonia

Martin Mičica, Sophie Eliet, Mathias Vanwolleghem, Roman Motiyenko, Anastasia Pienkina, Laurent Margulès, Kamil Postava, Jaromír Pištora, Jean-Francois Lampin

This study is aimed at the evaluation of THz gain properties in an optically pumped NH$_3$ gas. NH$_3$ molecules undergo rotational-vibrational excitation by mid-infrared (MIR) optical pumping provided by a MIR quantum cascade laser (QCL) which enables precise tuning to the NH3 infrared transition…

Control of local wetting by microscopic particles

Lizhong Mu, Harunori N. Yoshikawa, Daichi Kondo, Tetsuya Ogawa, Mayu Kiriki, Farzam Zoueshtiagh, Masahiro Motosuke, Toshihiro Kaneko, Ichiro Ueno

We perform experiments to investigate how particles of micro-meter size modify the wetting of a completely wettable solid surface. The motion of a macroscopic contact line (MCL) is observed to be altered in the region surrounding the particles. The MCL is accelerated locally by a single particle to…

A validated simulation of energy harvesting with piezoelectric cantilever beams on a vehicle suspension using Bond Graph approach

Barbara Lafarge, Sébastien Grondel, Christophe Delebarre, Eric Cattan

Nowadays, there is a combine effect of piezoelectric material performances and energy harvesting management strategy increase. As the same time, the energy consumption of electrical components and circuits decrease. Thus, this leads to a growing interest in recovering low energy level with…

Developing a MEMS device with built-in microfluidics for biophysical single cell characterization

Yuki Takayama, Grégoire Perret, Momoko Kumemura, Manabu Ataka, Samuel Meignan, Stanislav Karsten, Hiroyuki Fujita, Dominique Collard, Chann Lagadec, Mehmet Tarhan

This study combines the high-throughput capabilities of microfluidics with the sensitive measurements of microelectromechanical systems (MEMS) technology to perform biophysical characterization of circulating cells for diagnostic purposes. The proposed device includes a built-in microchannel that…

GaN-Based Laser Wireless Power Transfer System

Carlo de Santi, Matteo Meneghini, Alessandro Caria, Ezgi Dogmus, Malek Zegaoui, F Medjdoub, Boris Kalinic, Tiziana Cesca, Gaudenzio Meneghesso, Enrico Zanoni

The aim of this work is to present a potential application of gallium nitride-based optoelectronic devices. By using a laser diode and a photodetector, we designed and demonstrated a free-space compact and lightweight wireless power transfer system, whose efficiency is limited by the efficiency of…

Evidence of optically induced degradation in gallium nitride optoelectronic devices

Carlo de Santi, Alessandro Caria, Nicola Renso, Ezgi Dogmus, Malek Zegaoui, F Medjdoub, Gaudenzio Meneghesso, Enrico Zanoni, Matteo Meneghini

We provide experimental evidence that gallium-nitride-based optoelectronic devices can be affected by a photon-driven degradation mechanism unrelated to catastrophic optical damage. Any role of current in such degradation is excluded by stress tests under laser irradiation in the open-circuit…

Highly Sensitive Surface Acoustic Wave Magnetic Field Sensor Using Multilayered TbCo2/FeCo Thin Film

Aurelien Mazzamurro, Abdelkrim Talbi, Yannick Dusch, Omar Elmazria, Philippe Pernod, Olivier Bou Matar, Nicolas Tiercelin

Over the last decades, the use of Surface Acoustic Waves (SAW) has emerged as a promising technology in many applications such as filters, signal processing but also sensors. We report the fabrication and the characterization of a SAW delay line magnetic field sensor using uniaxial multi-layered…

Chapter 2 - Phonon monomode circuits

El Houssaine El Boudouti, Abdellatif Akjouj, L. Dobrzynski, Bahram Djafari-Rouhani, Housni Al-Wahsh, Gaëtan Lévêque, Yan Pennec

In this chapter, we discuss the vibrational properties of phononic circuits that can be described in the framework of discrete or continuous models. In the case of discrete media, we use the phonon discrete model within the Green’s function method described in Chapter 1 and give the surface…
