In this paper, we introduce a gas sensor concept consisting of a nanostructured gold grating coupled with a Distributed Bragg Reflector. This coupling makes it possible to obtain plasmonic Tamm states where excitation is possible at normal incidence and does not require the use of Kretschmann…

Reliable and robust integration of SAW strain sensor through reflow soldering

Othmane Marbouh, A. Mazzamurro, Y. Dusch, O. Bou Matar, N. Tiercelin, V. Maurice, P. Pernod, R. Viard, D. Laloy, K. Ettihir, A. Tounzi, A. Benabou, A. Talbi

Surface Acoustic Wave (SAW) sensors represent a prominent technological avenue for quantifying mechanical stress-induced deformations. Nonetheless, the integration of these Micro-Electro-Mechanical Systems (MEMS) sensors remains an complex challenge. Consequently, a common approach within a…

Exploring the properties of higher-order Tamm plasmons for liquid and gas detection

O. Haidar, Baptiste Mathmann, Y. Dusch, Mohamed Boutghatin, E. Boudouti, G. Lévêque, A. Mir, A. Akjouj, A. Talbi

In this study, we present a numerical analysis of the higher-order Tamm plasmons for the design of a gas and liquid sensor. These plasmons are induced by a structure consisting of a cavity placed between the SiO2/Si3N4 Bragg grating and a finite layer of gold. This configuration is excited without…

Fabry-Pérot and Friedrich-Wintgen bound states in the continuum in a photonic triple-stub cavity

Yamina Rezzouk, Soufyane Khattou, Mohamed El Ghafiani, Madiha Amrani, El Houssaine El Boudouti, Abdelkrim Talbi, Bahram Djafari-Rouhani

Bound states in the continuum (BICs) are zero-width (infinite lifetime) trapped eigenmodes that remain conf ined in the system even though they coexist with a continuum of extended states. The resulting high-frequency resonances may have significant applications in photonic integrated circuits,…

Thermoelectric Properties of Benzothieno-Benzothiophene Self-Assembled Monolayers in Molecular Junctions

Sergio Gonzalez-Casal, Rémy Jouclas, Imane Arbouch, Yves Geerts, Colin van Dyck, Jérôme Cornil, Dominique Vuillaume

We report a combined experimental (C-AFM and SThM) and theoretical (DFT) study of the thermoelectric properties of molecular junctions made of self-assembled monolayers on Au of thiolated benzothieno-benzothiophene (BTBT) and alkylated BTBT derivatives (C8-BTBT-C8). We measure the thermal…

Fault detection and localization in unshielded twisted pair cable based on observability analysis and reflectometry experimental measurements.

Hermine Judith Idellette Som, Vincent Cocquempot, Virginie Degardin

In this paper, an efficient method is proposed for detecting and locating a soft fault, i.e. a physical degradation, in a Y -shaped network of unshielded twisted pair cables. The method uses jointly the observability analysis and time-frequency domain reflectometry experimental measurements. The…

Electrochemical impedance spectroscopy of an evolving conducting polymer dendrite in water

Antoine Baron, Sébastien Pecqueur

Deposition of PEDOT:PSS is triggered alternatively on two gold wires distant of 240 µm from each other. The gold wires are immersed in a drop of water containing 10 mM of EDOT, 1 mM of sodium polystyrene sulfonate (NaPSS) and 10 mM of benzoquinone (BQ). The growth is captured with a camera and the…

Switchable SAW Resonators and Ladder Filters Composed of Interdigitated Combs

R. Alcorta Galván, Charles Croënne, Bertrand Dubus, B. Loiseaux, E. Eustache, M. Bertrand, A.-C. Hladky-Hennion

This work presents the development of switchable SAW resonators fabricated on a LiNbO3 substrate, which use the Electrical Bragg Bandgap concept to control the resonance frequency. The modification of the electrical condition of electrode arrays shifts their bandgap center frequency which in turn…
