Acoustic dispersive prism

Juan Ramon Mosig, Hervé Lissek, Sami Driss Karkar, Seyyed Hussein Seyyed Esfahlani

The optical dispersive prism is a well-studied element, which allows separating white light into its constituent spectral colors, and stands in nature as water droplets. In analogy to this definition, the acoustic dispersive prism should be an acoustic dev ...

Optical prism for creating multiple views of an image

Theo Lasser, Marcel Leutenegger, Stefan Geissbuehler

Optical prism comprising two external parallel and reflecting surfaces, one internal interface, parallel to said surfaces and acting as light splitter; said prism furthermore comprising an entrance side forming an angle β with respect to said interface and ...

Frequency comb generation in the green using silicon nitride microresonators

Tobias Kippenberg, Michail Zervas, Nicolas Volet, Hairun Guo, Martin Hubert Peter Pfeiffer

Optical frequency combs enable precision measurements in fundamental physics and have been applied to a growing number of applications, such as molecular spectroscopy, LIDAR and atmospheric trace-gas sensing. In recent years, the generation of frequency co ...

Airborne hyperspectral sensor radiometric self-calibration using near-infrared properties of deep water and vegetation

Bertrand Merminod, Vincent Maurice Nouchi, Kevin Sylvain Barbieux

Retrieving the water-leaving reflectance from airborne hyperspectral data implies to deal with three steps. Firstly, the radiance recorded by an airborne sensor comes from several sources: the real radiance of the object, the atmospheric scattering, sky an ...

Magnesium plasmonics for UV applications and chiral sensing

Peer Fischer, Hyeonho Jeong

We demonstrate that chiral magnesium nanoparticles show remarkable plasmonic extinction- and chiroptical-effects in the ultraviolet region. The Mg nanohelices possess an enhanced local surface plasmon resonance (LSPR) sensitivity due to the strong dispersi ...

Two-dimensional polymer grating and prism on Bloch surface waves platform

Hans Peter Herzig, Elsie Barakat, Libo Yu, Joab Di Francesco

A one-dimensional photonic crystal sustaining Bloch Surface Waves (BSWs) is used as a platform for two-dimensional integrated optics. The dielectric platform shows low loss, long propagation distance and high surface field enhancement. In order to study th ...

Near Field Investigation of Bloch Surface Based Platform for 2D Integrated Optics

Hans Peter Herzig, Elsie Barakat, Richa Dubey

Dielectric multilayers sustaining Bloch surface waves (BSWs) are considered as a novel platform for two dimensional (2D) integrated optics. The dielectric platform is exploited to manipulate surface waves by patterning 2D dielectric optical components on t ...

Towards an incoherent off-axis digital holographic microscope

Christian Depeursinge, Frédéric Montfort

We propose and experimentally demonstrate a system in which off-axis digital holographic microscopy is realized using a broadband illumination source. Single-shot holographic measurements are enabled, while the coherence noise is removed thanks to the broa ...

Large-scale sub-100 nm compound plasmonic grating arrays to control the interaction between localized and propagating plasmons

Olivier Martin, Thomas Gerd Siegfried, Arash Farhang

Compound plasmonic resonances arise due to the interaction between discrete and continuous metallic nanostructures. Such combined nanostructures provide a versatility and tunability beyond that of most other metallic nanostructures. In order to observe suc ...

Spectral cola or how to turn green laser light red

Xavier François Mettan, Thibaud Humair, Csaba Forro

A green laser pointer shone through a glass of cola will appear red when looking from above the glass. Lowering the laser so that it is deeper in the cola, the colour will vary from orange to deep red. Fluorescence and absorption spectra were recorded cons ...
