Piezoelectric micro-machined ultrasonic transducer (pMUT) for energy harvesting

Karim Dogheche, B. Cavallier, P. Delobelle, L. Hirsinger, S. Ballandras, Eric Cattan, Denis Remiens, M. Marzencki, B. Charlot, Skandar Basrour

Micro-electromechanical devices dedicated to energy scavenging purpose have yield an increasing interest for a few years. In this paper we report on the fabrication of PZT/Si piezoelectric micro-machined ultrasonic transducers (pMUT) first designed to ultrasonic imaging applications that may be...

Photonic devices based on preferential etching

Bob Bellini, Jean-François Larchanché, Jean-Pierre Vilcot, Didier Decoster, Romeo Beccherelli, Antonio D’alessandro

We introduce a design concept of optical waveguides characterized by a practical and reproducible process based on preferential etching of crystalline silicon substrates. Low-loss waveguides, spot-size converters, and power dividers have been obtained with polymers. We have also aligned liquid...
