Application of micro particle shadow velocimetry mu PSV to two-phase flows in microchannels

John Richard Thome, Navid Borhani, Sepideh Khodaparast

Micro particle shadow velocimetry (mu PSV) is performed in the present study for simultaneous velocity measurement and interface tracking in both liquid-liquid and gas-liquid two-phase flows through circular microchannels of 5001 mu m diameter. The back-li ...

Investigation of ultra-thin waveguide arrays on a Bloch surface wave platform

Hans Peter Herzig, Elsie Barakat, Libo Yu

Ultra-thin polymer optical waveguide couplers for integrated optics based on Bloch surface waves (BSWs) are presented. Desirable BSW guiding properties, such as low loss and long propagation distance, are observed. The waveguide thickness is on the order o ...

Towards highest spectral efficiency: Optical sinc-shaped Nyquist pulses generation from rectangular frequency comb

Luc Thévenaz, Camille Sophie Brès, Marcelo Alfonso Soto Hernandez, Mohammad Amin Shoaie, Mohammad Mehdi Alem Karladani

In this paper, we review a method to produce optical sinc-shaped Nyquist pulses with unprecedented quality. The method is based on the synthesis of a rectangular shaped and phase-locked frequency comb from a combination of intensity modulators. The result ...

Lattice dynamics and antiferroelectricity in PbZrO3 tested by x-ray and Brillouin light scattering

Nava Setter, Alexander Tagantsev, Kaushik Vaideeswaran

We report the results of a comprehensive study of the critical dynamics of the classical perovskite antiferroelectric PbZrO3. The combination of inelastic x-ray and diffuse x-ray scattering techniques and Brillouin light scattering was used. It is found th ...

A proposal for fs-electron microscopy experiments on high-energy excitations in solids

Fabrizio Carbone, Luca Piazza

Recent advances in ultrafast technology enable both the study and the control of materials properties thanks to the ability to record high temporal resolution movies of their transformations, or the ability to generate new states of matter by selecting ad ...

Experimental determination of the permeability of engineering textiles: Benchmark II

Véronique Michaud, Eliazar Rodriguez Garcia, Suzanne Godelieve Alphonsine Verheyden, Benoît Louis

In this second international permeability benchmark, the in-plane permeability values of a carbon fabric were studied by twelve research groups worldwide. One participant also investigated the deformation of the tested carbon fabric. The aim of this work w ...

Data transmission in long-range dielectric-loaded surface plasmon polariton waveguides

Svyatoslav Kharitonov, Ashwani Kumar

We demonstrate the data transmission of 10 Gbit/s on-off keying modulated 1550 nm signal through a long-range dielectric-loaded surface plasmon polariton waveguide structure with negligible signal degradation. In the experiment the bit error rate penalties ...

How color, regularity, and good Gestalt determine backward masking

Michael Herzog, Bilge Sayim, Mauro Manassi

The strength of visual backward masking depends on the stimulus onset asynchrony (SOA) between target and mask. Recently, it was shown that the conjoint spatial layout of target and mask is as crucial as SOA. Particularly, masking strength depends on wheth ...

Optical and morphological characterisation of low refractive index materials for coatings on solar collector glazing

Jean-Louis Scartezzini, Andreas Schueler, Marie Schaer, Martin Joly, Stefan Mertin, Estelle De Chambrier, Virginie Hody-Le Caër

Nanostructured coatings based on the elements Si, O, Mg, and F have been deposited as thin films by solegel dip-coating in a particle-free atmosphere. The refractive index of the prepared SiO2 and quaternary MgeFeSieO thin films has been determined from sp ...
