Enhanced strength and toughness of bulk ultrafine grained Cu by nacre-inspired lamellar structure

An ultrafine grained (UFG) bulk Cu with a novel nacre-inspired lamellar structure containing nano-bridges and aligned nanopores at inter-lamellar interfaces was fabricated by consolidation of a nanocrystal-attached ultrathin Cu flake powder by spark plasma ...

Dot pattern generation using thick sinusoidal phase grating under Gaussian beam illumination

Toralf Scharf, Maryam Yousefi

Far-field dot pattern generation is analyzed for a Gaussian beam source that illuminates a sinusoidal phase grating which is placed at a certain distance behind the beam waist. We obtain a bigger field of view with more numbers of points using a Gaussian b ...

Ultra-thin Bloch-surface-wave-based reflector at telecommunication wavelength

Hans Peter Herzig, Richa Dubey, Babak Vosoughi Lahijani

We experimentally demonstrate the optical properties of gratings engraved in a single-mode waveguide fabricated on top of a dielectric multilayer platform. The structure can be approached as a reflector for Bloch-surface-wavebased two-dimensional optical s ...

Light Scattering Enhancement at the Absorption Edge in Dewetting Droplets of Cyanine Dyes

Frank Nüesch, Jakob Heier, Florent Alexandre Boudoire

Diffraction properties of thin films of dewetted cyanine dye droplets are investigated and related to the complex refractive index. Strong changes in the index of refraction are often found near the absorption edge of organic dyes. Within a small window of ...

High-power femtosecond Raman frequency shifter

Christoph Peter Hauri, Mostafa Shalaby

We report on the generation of broadband, high-energy femtosecond pulses centered at 1.28 mu m by stimulated Raman scattering in a pressurized hydrogen cell. Stimulated Raman scattering is performed by two chirped and delayed pulses originating from a mult ...

From spider webs to a fibre-optic chemical sensor

Luc Thévenaz, Isabelle Dicaire, Kenny Hey Tow, Desmond Chow Ming Chia

From the spider’s perspective, silk is not only a building material but also a safety net, a weapon and a sensory organ to detect the presence of prey on its web. For scientists, dragline silk - directly extracted from spiders - is a tough, biodegradable a ...

Potential of magnetron sputtered magnesium fluoride containing thin films for the multilayer design of coloured coatings for solar collector glazing

Jean-Louis Scartezzini, Paul Muralt, Stefan Mertin

In this work, the potential of magnetron sputtered magnesium fluoride (MgF2) and MgF2 containing composite coatings for coloured solar collector glazing is investigated. Coloured thin-film interference coatings on the reverse side of the collector cover gl ...

Biomimetic Pieris rapae’s Nanostructure and Its Use as a Simple Sucrose Sensor

Philippe Renaud, David Vincent Bonzon, Rodrigo Martinez Duarte

iomimetics often provides efficient ways to create a product incorporating novel properties. Here we present the replication of the Pieris rapae butterfly optical structure. This butterfly has white wings with black spots. The white coloration is produced ...
