Optimisation de guides optiques à absorption linéaire

Vincent Magnin, Joseph Harari

Il est remarquable d’obtenir une absorption optique quasiment constante. Cela est rendu possible par l’utilisation de nano-guides optiques dont la largeur du cœur peut être réduite avec le profil voulu afin de déconfiner progressivement le mode optique.

S-parameters characterization of GaN power transistors for high frequency power converters design

Loris Pace, Nicolas Defrance, Arnaud Videt, Nadir Idir, Jean-Claude de Jaeger

Gallium Nitride (GaN) power devices that have been developed these recent years are ideals candidates for high frequency power conversion, leading to a reduction of size, cost and weight of power converters. This work presents a new modeling methodology of GaN power transistors based on...

[Invited] LbL based PEDOT:PSS microactuators and microsensors

Kätlin Rohtlaid, Cedric Plesse, Giao T.M. Nguyen, Caroline Soyer, Eric Cattan, Frederic Vidal

Conducting polymers (CPs) are functional materials that respond to external electrical stimulus and are able to generate reversible contraction and expansion which leads to changing the shape or the size of these materials. They are soft, lightweight, easily processed and manufactured which has...

Non-linear dynamic modeling of ultrathin conducting polymer actuators

Tan Ngoc Nguyen, Yuta Dobashi, Caroline Soyer, Cedric Plesse, Giao T.M. Nguyen, Frederic Vidal, Eric Cattan, Sébastien Grondel, John D.W. Madden

Trilayer ionic EAP actuators exhibit nonlinear electrical and mechanical properties as a function of their oxidation state making it more challenging to accurately predict their mechanical behavior. In this study, an analytical multi-physics model of the conducting polymer actuators is proposed to...
