Acousto-Optical Tunable Filter design for efficient diffraction of unpolarised light

Samuel Dupont, Jean-Claude Kastelik, J. Vanhamel, E. Dekemper

Diffraction of optical waves by an acoustic grating is a well-known phenomenon that enables the design of versatile devices useful in photonic systems. For example, acousto-optic tunable filters (AOTFs) can be dynamically tuned by radio-frequency signals. Among possible material choice,…

Design of a Radio Frequency Compensation System, using the Electrical Characterisation of a Multi-Transducer Acousto-Optical Tunable Filter

J. Vanhamel, Samuel Dupont, Jean-Claude Kastelik, E. Dekemper

Acousto-Optical Tunable Filters (AOTFs) make use of the interaction between sound and light. To generate an ultrasound diffraction grating, a Radio-Frequency (RF) signal is applied to a piezoelectric transducer. The optical pass band can be controlled by adapting the properties of this transducer…

Passive sensor network resycnhronization applied for SHM

O. Bouchakour, L. Chehami, E. Moulin

Recent research works in passive Structural Health Monitoring (SHM) have been able to take advantage of ambient noise by cross-correlating raw data recorded by sensor array. For that, the acquired signals must be synchronized with respect to each other. In other words, it is essential to set up a…

Hyperuniform versus Poisson Distributions in Random Metasurfaces at Infrared Wavelengths

Eric Lheurette, Roman Buisine, Olivier Vanbesien, David Dereudre, Ludovic Burgnies, Thibault Deletang, Benoît Cluzel

In this communication, we compare the relevance of two kinds of random distributions of Metal Isolant Metal (MIM) resonators describing a metasurface for extinction of an impinging incident signal at infrared wavelengths. The patterns are generated by home-made codes prior to numerical simulations…

CHARACTERIZATION OF ADHESION BY RAYLEIGH MODES GENERATED AND DETECTED BY LASERS

Mustapha Baher, Meriem Chrifi Alaoui, Frédéric Jenot, Mohammadi Ouaftouh, Marc Duquennoy

Adhesion is the ability of dissimilar particles to clutch together and is used to describe the contact between two interfaces. It is often considered as the predominant factor for coating reliability in thin-film technologies. Many techniques have been established to estimate the coating-substrate…

Improving off-state capacitance of SOI-CMOS RF switches: how good are air microcavities?

Daniel Gheysens, Alain Fleury, Stéphane Monfray, Frédéric Gianesello, Philippe Cathelin, Jean-François Robillard, David Troadec, Emmanuel Dubois

This paper investigates the reduction of the off-state capacitance (COFF) of SOI-CMOS RF switches induced by the introduction of air microcavity in the back-end interconnection network. A detailed methodology combining electromagnetic and semiconductor transport simulations is used to separately…
