Characterization of Photonic Crystal Waveguides Based on Fabry-Pérot Interference

Hans Peter Herzig, Ross Stanley, Iwan Märki

We present two methods based on the analysis of Fabry-Perot interference for a detailed characterization of a 90degrees corner in a two-dimensional photonic crystal waveguide fabricated in a thin Si membrane. These methods are a means of identifying the cr ...

Effect of micromechanical stimulations on osteoblasts: development of a device simulating the mechanical situation at the bone-implant interface

Dominique Pioletti, Lalaonirina Rakotomanana Ravelonarivo

Many experimental models have been developed to investigate the effects of mechanical stimulation of cells, but none of the existing devices can simulate micromotions at the cellular-mechanical interface with varying amplitudes and loads. Osteoblasts are s ...

Series connection of supercapacitors, with an active device for equalizing the voltages

Alfred Rufer, Philippe Barrade

The paper presents an active sharing device, for equalizing the voltages across a series connection of supercapacitors. This ensures an optimal value for the stored energy. Based on a buck-boost topology, this device is designed and controlled to propose a ...
