2x2 InP optical switching matrix based on carrier-induced effects for 1.55-µm applications

Malek Zegaoui, Nargess Choueib, Joseph Harari, Didier Decoster, V. Magnin, X. Wallart, Jean Chazelas

This letter demonstrates a 2 × 2 low optical crosstalk and low power consumption switching matrix device based on carrier-induced effects on an InP substrate. The matrix device comprises two digital optical switches (DOSs) with a wide multimode Y-junction associated with a sinusoidal passive…

Nanowire biocompatibility in the brain - Looking for a needle in a 3D stack

Cecilia Eriksson-Linsmeier, Christelle Prinz, Lina M. E. Pettersson, Philippe Caroff, Lars Samuelson, Jens Schouenborg, Lars Montelius, Nils Danielsen

We investigated the brain-tissue response to nanowire implantations in the rat striatum after 1, 6, and 12 weeks using immunohistochemistry. The nanowires could be visualized in the scar by confocal microscopy (through the scattered laser light). For the nanowire-implanted animals, there is a…

In-plane polarities of nonpolar wurtzite epitaxial films deposited on m- and r-plane sapphire substrates

Philippe Vennéguès, Tiankai Zhu, Z. Bougrioua, Denis Martin, J. Zuniga-Perez, Nicolas Grandjean

The in-plane polarities of GaN and ZnO non-polar films deposited on r - and m-sapphire are compared. The polarity is unique on r-sapphire and mixed on m-sapphire because the direction on the substrate surface parallel to the wurztite c-direction is polar in the first case and nonpolar in the second…

Fast relaxation of hot carriers by impact ionization in semiconductor nanocrystals : role of defects

Guy Allan, Christophe Delerue

We present calculations predicting that defects at the surface of semiconductor nanocrystals have a strong influence on the dynamics of hot carriers after photoexcitation. The relaxation of excited carriers by impact ionization of carriers trapped on deep levels is efficient, in particular in the…
