Mueller matrix optical and magneto-optical characterization of Bi-substituted gadolinium iron garnet for application in magnetoplasmonic structures

L. Halagacka, K. Postava, Mathias Vanwolleghem, Francois Vaurette, Jamal Ben Youssef, B. Dagens, J. Pistora

A ferromagnetic garnet, used as a magneto-optical (MO) material in magneto-photonic and magneto-plasmonic structures, is characterized. We present a general procedure to determine optical and magneto-optical functions of the magneto-optic garnet by using Mueller matrix ellipsometry. In the first…

Multi-phonon scattering processes in one-dimensional anharmonic biological superlattices : understanding the dissipation of mechanical waves in mineralized tissues

Pierre-Yves Guerder, Alix C. Deymier-Black, Nichlas Z. Swinteck, Jerome O. Vasseur, Olivier Bou Matar, Krishna Muralidharan, Pierre A. Deymier

The scattering of elastic waves in a one dimensional phononic (PnC) crystal composed of alternate collagen and hydroxy-apatite constituent layers is studied. These superlattices are metaphors for mineralized tissues present in bones and teeth. The collagen is treated as an open system elastic…

On the effect of δ-doping in self-switching diodes

Andreas Westlund, Ignacio Iñiguez-De-La-Torre, Per-Åke Nilsson, Tomas González, Javier Mateos, Paul Sangaré, Guillaume Ducournau, Christophe Gaquière, L. Desplanque, Xavier Wallart, Jan Grahn

Lowering the carrier concentration is presented as a way to considerably improve the performance of self-switching diode (SSD) detectors. A physics-based theoretical model was used to derive an expression for the responsivity of SSDs as a function of carrier concentration, mobility, and design…

Optimized V-shape design of GaN nanodiodes for the generation of Gunn oscillations

J.F. Millithaler, I. Iniguez-De-La-Torre, A. Iniguez-De-La-Torre, T. Gonz Alez, P. Sangaré, Guillaume Ducournau, Christophe Gaquière, J. Mateos

In this work, recent advances in the design of GaN planar Gunn diodes with asymmetric shape, socalled self-switching diodes, are presented. A particular geometry for the nanodiode is proposed, referred as V-shape, where the width of the channel is intentionally increased as approaching the anode.…
