Polarization controlled directional propagation of Bloch Surface Wave

Hans Peter Herzig, Myun Sik Kim, Maria-Pilar Bernal

Bloch surface waves (BSWs) are recently developing alternative to surface plasmon polaritons (SPPs). Due to dramatically enhanced propagation distance and strong field confinement these surface states can be successfully used in on-chip all-optical integra ...

2D Optics on Bloch Surface Waves (BSWs) Based Platform: Polymer Lens and Prism

Hans Peter Herzig, Vincent Paeder, Libo Yu, Tristan Sfez

In this work, we use a novel platform concept based on Bloch Surface Waves (BSWs) and manipulate the BSWs propagation with two-dimensional (2D) dielectric patterns deposited on it. The concept opens a way to realize 2D integrated all-optics systems includi ...

Fluid-structure coupling for an oscillating hydrofoil

François Avellan, Mohamed Farhat, Philippe Ausoni, Olivier Braun

Fluid-structure investigations in hydraulic machines using coupled simulations are particularly time-consuming. In this study, an alternative method is presented that linearizes the hydrodynamic load of a rigid, oscillating hydrofoil. The hydrofoil, which ...

Laser perfusion imaging system for acquiring flow-related images of object for medical diagnosis comprises coherent light source and image sensor(s) made by randomly addressed two-dimensional array of integrating photodetectors

Theo Lasser

An instrument for high-speed laser perfusion imaging comprises a laser source, a detector, a signal-processing unit, data memory, and a screen to display the results. A section of the sample surface is illuminated with laser light; the reemitted light from ...

Reed vibration in lingual organ pipes without the resonators

Vibrations of plucked and blown reeds of lingual organ pipes without the resonators have been investigated. Three rather surprising phenomena are observed: the frequency of the reed plucked by hand is shifted upwards for large-amplitude plucking, the blown ...
