Optoelectronic components and integrated circuits including up and down conversion techniques and hybrid integration technology

Didier Decoster, Samuel Dupont, V. Magnin

Microwave optical links can be considered as basic bricks for some emerging system applications such as optically supplied microwave antennas. Emitters, optical switching matrices, high speed photodetectors and specific components for up or down conversion, are generic devices or functions for...

Evidence of an impurity band at an n-GaN/sapphire interface

C. Mavroidis, J.J. Harris, R.B. Jackman, Z. Bougrioua, I. Moerman

We report on temperature-dependent differential Hall-effect and resistivity measurements, between 10 and 300 K, on a silicon-doped GaN epitaxial layer grown by metalorganic chemical vapor deposition on a sapphire substrate. Reactive ion etching has been used to enable Hall measurements to be taken...

Statistical Estimation of Fast Varying Channels for Cellular Mobile Telecommunications Systems

Iyad Dayoub, M. Zaizouni, Atika Rivenq, Jean-Michel Rouvaen

The time variant environment in fast channels severely impacts on the performances of classical equal-ization techniques. A method is proposed here to circumvent this problem, particularly in the severe channel with fast behaviour. To improve the Bit Error Rate (BER) at the receiver, a new approach...

Adsorption behavior of conjugated {C}3-oligomers on Si(100) and HOPG surfaces

Gauthier Mahieu, B. Grandidier, Didier Stiévenard, Christophe Krzeminski, Christophe Delerue, C. Martineau, Jean Roncali

A pi-conjugated {C}3h-oligomer involving three dithienylethylene branches bridged at the meta positions of a central benzenic core has been synthesized and deposited either on the Si(100) surface or on the HOPG surface. On the silicon surface, scanning tunneling microscopy allows the observation of...

Dimensionality-dependent self energy corrections and exchange-correlation potential in semiconductor nanostructures

Christophe Delerue, Guy Allan, Michel Lannoo

We study the quasiparticle gap in semiconductor nanostructures versus dimensionality and compare it to the value obtained in the local density approximation. We first develop general arguments based on the GW approach which we then substantiate numerically by a tight binding version of this theory...

Microelectromechanical variable-bandwidth if frequency filters with tunable electrostatical coupling spring

Dimitri Galayko, Andreas Kaiser, Lionel Buchaillot, Dominique Collard, Chantal Combi

This paper describes the theory, design and test of a novel architecture of highly-selective micromechanical filters employing electrostatically coupled resonators with floating or biased coupling electrodes. This original method avoids the use of mechanical coupling springs thus extending the...

A low complexity suboptimal MIMO receiver : the combined ZF-MLD algorithm

V. Pammer, Yves Delignon, Wadih Sawaya, David Boulinguez

Recently, wireless technologies have known an increasing success, thus becoming an interesting field for study. One of the topics of research are multiple antenna arrays. Signal recovery in that case is not obvious. Different methods with different performances have been suggested. From a...
