RANS computations of tip vortex cavitation

Some two-dimensional (2D) exfoliated zeolites are single- or near single-unit cell thick silicates that can function as molecular sieves. Although they have already found uses as catalysts, adsorbents and membranes precise determination of their thickness ...

Multilevel Micro-Structuring of Glassy Carbon for Precision Glass Molding of Diffractive Optical Elements

Hans Peter Herzig, Toralf Scharf, Karin Prater

A consumer market for diffractive optical elements in glass can only be created if high efficient elements are available at affordable prices. In diffractive optics the efficiency and optical properties increases with the number of levels used, but in the ...

Transflective holographic film for head worn display

Jürgen Brugger, Christophe Moser, Eric Tremblay, Victor Javier Cadarso Busto, Jonas Grossenbacher

A display panel assembly comprises a transflective holographic screen, i.e., a transparent screen that reflects light from a projection system, comprising at least a volume hologram, a first protective element and a second protective element, each arranged ...

Femtosecond diffractive imaging of structures, charge and spin textures

Giulia Fulvia Mancini

The study of the dynamical evolution of a system, e.g. a chemical reaction or a phase transition, has become nowadays a subject of growing scientific interest. The direct observation of the steps and the structural changes through which chemical reactions ...

Serial snapshot crystallography for materials science with SwissFEL

Philip Pattison

New opportunities for studying (sub) microcrystalline materials with small unit cells, both organic and inorganic, will open up when the X-ray free electron laser (XFEL) presently being constructed in Switzerland (SwissFEL) comes online in 2017. Our synchr ...

Methods and apparatus for imaging with multimode optical fibers

Demetri Psaltis, Christophe Moser, Ioannis Papadopoulos, Salma Farahi

A multimode waveguide illuminator and imager relies on a wave front shaping system that acts to compensate for modal scrambling and light dispersion by the multimode waveguide. A first step consists of calibrating the multimode waveguide and a second step ...

Up-scalable plasmonic and diffractive nanostructures

Fabian Michael Lütolf

Since most of the academic photonic and plasmonic nanostructures are based on slow and expensive electron beam lithography processes, there is a need for innovative alternatives suitable for industrial manufacturing. Large areas need to be patterned with a ...

Research in the field of single biopolymers using scanning probe microscopy

Andrey Mikhaylov

Current thesis is devoted to the investigation of biopolymers using AFM, a well established and widely used technique. To begin with, we studied processing of AFM images and its automation. Our software product, DNA Trace, permit one to quickly extract sci ...

High-fidelity visualization of formation of volume nanogratings in porous glass by femtosecond laser irradiation

Yves Bellouard, Min Huang, Ya Cheng

Formation of self-organized nanogratings in bulk glasses with femtosecond laser pulses is one of the most intriguing phenomena in the interactions of light with transparent materials. With the feature sizes far beyond the optical diffraction limit, these n ...

Organic-inorganic-hybrid-polymer microlens arrays with tailored optical characteristics and multi-focal properties

Jürgen Brugger, Victor Javier Cadarso Busto, Loïc Jacot-Descombes

Plano-convex microlens arrays of organic-inorganic polymers with tailored optical properties are presented. The fine-tuning of each microlens within an array is achieved by confining inkjet printed drops of the polymeric ink onto pre-patterned substrates. ...
