Development of high-speed, patch-antenna intersubband photodetectors at 10.3um

Q. Lin, M Hakl, S Pirotta, R. Colombelli, W. Wan, H Li, J. Cao, Jean-Francois Lampin, Emilien Peytavit, S Barbieri

We present our work towards the development of high-speed, GaAs-AlGaAs multi-quantum wells photodetectors at 10.3m, based on two-dimensional arrays of patch-antenna resonators. First, the results of FDTD simulations will be presented that allowed to optimize the patch array geometry and fabricate…

Reservoir Computing for Sensing - an Experimental Approach

Dawid Przyczyna, Sébastien Pecqueur, Dominique Vuillaume, Konrad Szacilowski

The increasing popularity of machine learning solutions puts increasing restrictions on this field if it is to penetrate more aspects of life. In particular, energy efficiency and speed of operation is crucial, inter alia in portable medical devices. The Reservoir Computing (RC) paradigm poses as a…

An Integrated Photoacoustic Terahertz Gas Sensor

Mattias Verstuyft, Elias Akiki, Benjamin Walter, Marc Faucher, Mathias Vanwolleghem, Bart Kuyken

An on-chip gas detector that transduces absorbed terahertz light to a mechanical motion using photoacoustics is proposed. The silicon chip confines light in an optical cavity, wherein an acousto-mechanical cavity is housed. The concentration of a trace gas can be determined from the amplitude of a…

The Non-Ideal Organic Electrochemical Transistors Impedance

Sébastien Pecqueur, Ivor Lončaric, Vinko Zlatić, Dominique Vuillaume, Željko Crljen

Organic electrochemical transistors offer powerful functionalities for biosensors and neuroinspired electronics, with still much to understand on the time dependent behavior of this electrochemical device. Here, we report on distributed element modeling of the impedance of such microfabricated…

A Multiscale Numerical Model for Structures with Internal Frictional Contacts

Kevin Truyaert, Vladislav Aleshin, Steven Delrue, Koen van den Abeele

Abstract Many engineering applications are related to or deal with materials and systems having internal frictional contacts in their structure. The effects induced by these contacts, such as friction-induced heat generation, wear, nonlinear vibrations, etc., can be significant and cannot be…

Hyperfine Interactions and Slow Spin Dynamics in Quasi-isotropic InP-based Core/Shell Colloidal Nanocrystals

Annalisa Brodu, Mickaël Tessier, Damien Canneson, Dorian Dupont, Mariana V Ballottin, Peter C M Christianen, Celso de Mello Donega, Zeger Hens, Dmitri R Yakovlev, Manfred Bayer, Daniel Vanmaekelbergh, Louis Biadala

Colloidal InP core/sell nanocrystals are taking over CdSe-based nanocrystals, notably in optoelectronic applications. Despite their use in commercial device such as display screens, the optical properties of InP nanocrystals and especially their relation with the exciton fine structure remains…

Performance théorique d'un neurone à spikes Integrate-and-Fire

Anne Savard, Laurent Clavier, Francois Danneville, Christophe Loyez

Ce papier se concentre sur les performances théoriques d'un détecteur neuro-inspiré pour une communication numérique où le signal d'entrée est inférieur au seuil d'activation du neurone, rendant le bruit crucial pour la détection. Nous caractérisons dans un premier temps la…, This paper focuses on the theoretical performance of a neuro-inspired digital communication, where the input signal is below the activation threshold of the neuron, making the noise crucial for the detection. We first derive the error probability of a neuro-inspired detector build upon a single…

Allocation de puissance pour les réseaux radio cognitifs à relais

Anne Savard, Elena Veronica Belmega

Ce papier porte sur un problème d'allocation de puissance pour un réseau radio cognitif composé d'une paire utilisateur/destination primaire et secondaire ainsi que d'un relais aidant la communication entre l'utilisateur opportuniste et sa destination. Le système secondaire ne…, This paper addresses a power allocation problem in a relay-aided cognitive network that is composed by a primary and secondary source/destination pair and where a relay helps the communication of the secondary network. The optimal power allocation is derived under a minimum quality of service (QoS…
