Continuous-wave infrared optical gain and amplified spontaneous emission at ultralow threshold by colloidal HgTe quantum dots

Pieter Geiregat, Arjan J Houtepen, Laxmi Kishore Sagar, Ivan Infante, Felipe Zapata, Valeriia Grigel, Guy Allan, Christophe Delerue, Dries van Thourhout, Zeger Hens

Abstract Colloidal quantum dots (QDs) raise more and more interest as solution-processable and tunable optical gain materials. However, especially for infrared active QDs, optical gain remains inefficient. Since stimulated emission involves multifold degenerate band-edge states, population...

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...

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...

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...

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...

Adaptive Channel estimation technique for ITS-G5 inter- vehicular communication systems

Aymen Sassi, Yassin El Hillali, Atika Rivenq

In recent years, vehicle-to-Vehicle (V2V) and Vehicle-to-Infrastructure (V2I) communication systems, known as V2X technologies, have been the interest of several research works in road safety and traffic ergonomics. The evaluation of their performance is a substantial step before their probable...

Analytical model for the energy harvesting of a spherical sensor from ambient vibrations

Daher Diab, Fabrice Lefebvre, Georges Nassar, Nikolay Smagin, Adnan Naja, Fawaz El Omar

In this work an analytical model for the energy harvesting of an acoustic spherical sensor has been developed in the context to make it autonomous. Our spherical sensor is composed of two half-spheres of Plexiglas and a piezoelectric ring of PZ26 that can be used as exciter or sensor. For the...

IDTC Special Issue. Methods and Cognitive Modelling in the History and Philosophy of Science–&–Education

Raffaele Pisano

Generally speaking, virtual displacement or work concerns to a timely idea according to which a motion of a certain body is not the unique possible motion. The process of reducing this motion to a particular magnitude and concept, eventually minimizing as a hypothesis, can be traced back to the...
