Measuring the surface stress polar dependence

J. J Métois, A. Saul, P. Muller

Although measurements of the polar dependence of the surface free energy are easily available, measurements of the whole polar dependence of the surface stress of a crystal do not exist. Here, we present a procedure that allows the experimental determination of this dependence. For this purpose,...

Optical characterization of polychromatic organic light emitting diodes

David Troadec, André Moliton, Bernard Ratier, Rémi Antony, Roger C. Hiorns

Luminance and quantum yields of organic light emitting diodes (OLEDs) are generally calculated by using a hypothetic monochromatic emission even though the actual external emission is lower than the internal emission because of internal reflection, and is polychromatic. For organic materials, we...

A Closed-Form Formulation for the Total Power Radiated by a Single-Wire Overhead Line

Andrea Cozza, Flavio G. Canavero, Bernard Démoulin

A new analytical solution for the total power radiated by a single-wire line over a ground-plane is here proposed, for the special case of a lossless complex exponential current-distribution. The line is not assumed to be electrically short or “closed”, thus being suitable for assessing the...

11% efficiency 100 GHz InP-based heterostructure barrier varactor quintupler

T. Bryllert, A. Olsen, J. Vukusic, T.A. Emadi, M. Ingvarson, J. Stake, D. Lippens

A record conversion efficiency of 11.4% at 100 GHz using a heterostructure barrier varactor (HBV) quintupler is demonstrated. The quintupler is based on a microstrip circuit mounted in a full-height crossed-waveguide block. The nonlinear element consists of a planar HBV diode fabricated in InGaAs/...

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...

Design of microstrip to waveguide transition in the W band suitable antenna or integrated circuits connections

B.D. Nguyen, Claire Migliaccio, Christian Pichot, N. Rolland

This paper presents a millimeter waveguide-to-microstrip line transition based on E-mode coupling. It uses a standard W-band waveguide and a microstrip line made on alumina substrate. It has been designed for the center frequency of 94 GHz. A back-to-back transition has been done and measured...
