Radiative Quality Factor in Thin Resonant Metamaterial Absorbers

Nicolas Fernez, Ludovic Burgnies, Jianping Hao, Colin Mismer, Guillaume Ducournau, Didier Lippens, Eric Lheurette

Perfect electromagnetic absorption in an array of thin resonators is analyzed by means of the quality factor involving separately the contribution of losses and a coupling with free space. An equivalent electrical circuit based on an open-resonator model is introduced for an absorber made of…

[Invited] Study of the spectral bandwidth of a double-pass acousto-optic system

Justine Champagne, Jean-Claude Kastelik, Samuel Dupont, Joseph Gazalet

Acousto-optic tunable filters are known as efficient instruments for spectral and spatial filtering of light. In this paper, we analyze the bandwidth dependence of a double-pass filter. The interaction geometry chosen allows the simultaneous diffraction of the ordinary and the extraordinary optical…

Progress and opportunities in high-voltage microactuator powering technology towards one-chip MEMS

Yoshio Mita, Atsushi Hirakawa, Bruno Stefanelli, Isao Mori, Yuki Okamoto, Satoshi Morishita, Masanori Kubota, Eric Lebrasseur, Andreas Kaiser

In this paper, we address issues and solutions for micro-electro-mechanical-systems (MEMS) powering through semiconductor devices towards one-chip MEMS, especially those with microactuators that require high voltage (HV, which is more than 10 V, and is often over 100 V) for operation. We…

Optimization of SAW-type Surface Wave Ultrasonic Sensors for Ultrasonic SHM

Rafatou Takpara, Marc Duquennoy, Mohammadi Ouaftouh, Christian Courtois, Frédéric Jenot, Mohamed Rguiti

Surface acoustic waves (SAW) are particularly suited for effectively monitoring and characterizing a structure’s surfaces (condition of the surface, coating, thin layer, micro-cracks, etc.), and in some cases it is necessary to permanently keep the sensors on the structures to enable continuous…

Wavelength characterization of an acousto-optic notch filter for unpolarized near-infrared light

Jean-Claude Kastelik, Justine Champagne, Samuel Dupont, Konstantin B. Yushkov

A cascaded system of two acousto-optical cells is proposed and experimentally demonstrated for optical notch rejection filtering in the spectral range from 1400 nm to 1600 nm. Two similar paratellurite acousto-optical devices for unpolarized light are used in a free-space gap of a fiber line.…
