Theoretical and experimental evidence of Fano-like resonances in simple monomode photonic circuits

A. Mouadili, E.H. El Boudouti, A. Soltani, Abdelkrim Talbi, Abdellatif Akjouj, Bahram Djafari-Rouhani

A simple photonic device consisting of two dangling side resonators grafted at two sites on a waveguide is designed in order to obtain sharp resonant states inside the transmission gaps without introducing any defects in the structure. This results from an internal resonance of the structure when…

Global transmission and reflection coefficients of the ultrasonic component in porous media : a new approach

Georges Nassar, Amina Medjdoub, N. Saad

The purpose of this paper is to propose a new approach to determining the global ultrasonic transmission and reflection coefficients in a random porous medium. Boundary conditions at the interface of the medium were used to determine local transmission and reflection coefficients. A study of the…

Electron delay analysis and image charge effect in AlGaN/GaN HEMT on silicon substrate

Alain Agboton, N. Defrance, Philippe Altuntas, Vanessa Avramovic, Adrien Cutivet, Rezki Ouhachi, Jean-Claude de Jaeger, Samira Bouzid-Driad, Maher, Hassan, M. Renvoise, Peter Frijlink

A delay time analysis is carried out for SiN-passivated AlGaN/GaN High Electron Mobility Transistors (HEMTs) on silicon substrate featuring gate length of 90 nm. The influence of high parasitics in the access pads is considered using de-embedding procedure from the measured S parameters. From the…

Improvement of the oxidation interface in an AlGaAs/AlxOy waveguide structure by using a GaAs/AlAs superlattice

J.Y. Song, S. Bouchoule, G. Patriarche, E. Galopin, A.M. Yacomotti, E. Cambril, Q.G. Kou, David Troadec, J.J. He, J.C. Harmand

The wet oxidation from the mesa sidewalls of AlGaAs/GaAs epitaxial structures is investigated in details. In addition to the intended lateral oxidation of the Al-rich buried layer, we observe a parasitic vertical oxidation of the adjacent layers of lower Al content. This vertical oxidation produces…

The roles of biological interactions and pollutant contamination in shaping microbial benthic community structure

Haithem Louati, O. Ben Said, A. Soltani, P. Got, E. Mahmoudi, Cristiana Cravo-Laureau, Robert Duran, P. Aissa, O. Pringault

Biological interactions between metazoans and the microbial community play a major role in structuring food webs in aquatic sediments. Pollutants can also strongly affect the structure of meiofauna and microbial communities. This study aims investigating, in a non-contaminated sediment, the impact…

Addition of HfO$_2$ interface layer for improved synaptic performance of phase change memory (PCM) devices

M. Suri, O. Bichler, Q. Hubert, L. Perniola, V. Sousa, C. Jahan, D. Vuillaume, C. Gamrat, B. de Salvo

In this work, we will focus on the use of phase change memory (PCM) to emulate synaptic behavior in emerging neuromorphic system-architectures. In particular, we will show that the performance and energy-efficiency of large scale neuromorphic systems can be improved by engineering individual PCM…
