Tunable optical filter of porous silicon as key component for a MEMS spectrometer

Philippe Renaud, Sandra Schweizer, Gerhard Lammel

We present a microspectrometer based on a tunable interference filter for infrared or visible light that scans the desired part of the spectrum within milliseconds. A single pixel detector measures serially the intensity at selected wavelengths. This conce ...

Les Matériaux Actifs à Propriétés Acoustiques Variables

Hervé Lissek

This work deals with the concept of active materials with variable acoustic properties, dedicated to room acoustics applications. This concept is based on an acoustic impedance active control principle by hybrid motionnal feedback, applied on an electroaco ...

Surface reactivity of highly vibrationally excited molecules prepared by pulsed laser excitation: CH4 (2 nu(3)) on Ni(100)

Thomas Rizzo, Rainer Beck, Plinio Maroni, Mathieu Schmid

We report state resolved sticking coefficients for highly vibrationally excited CH4 on Ni(100) at well-defined kinetic energies in the range of 12-72 kJ/mol. Incident methane molecules are prepared by pulsed laser radiation in single rovibrational levels o ...

Direct processes in the energy deposition of protons in silicon

The low energy part of proton induced SBD spectra have higher number of counts than expected from p+Si reactions. This is the case for all proton incident angles but the effect increases when approaching grazing angles. The effect is shown to be mainly due ...

Angle And Space Multiplexed Holographic Storage Using The 90-Degrees Geometry

Demetri Psaltis

The 90-degrees geometry - with reference and signal beams entering orthogonal crystal faces - is used to angularly multiplex up to 500 holograms at each of 8 spatially multiplexed locations in a LiNbO3 crystal. A segmented mirror array and a 2D mechanical ...
