Absorption Enhancement in Solar Cells With Periodic Interface Textures of Asymmetric Shape

Christophe Ballif, Franz-Josef Haug, Karin Söderström

We investigate light scattering interface textures for solar cells with the intention to obtain a more fundamental understanding of the absorption enhancement. Therefore, we study simplified structures with the periodic interface texture of sinusoidal and ...

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 ...

Closed-form expressions for modeling diffraction at printed dipole-based FSS

Juan Ramon Mosig, Maria Garcia Vigueras

This paper presents analytical expressions to model the diffraction of plane-waves at planar 2-D distributions of printed dipoles. In contrast to other available analytical or quasi-analytical models, this approach rigorously captures the main underlying p ...

Influence of reflecting walls on edge diffraction simulation in geometrical acoustics

Dirk Schröder

Edge diffraction can be introduced into Geometrical Acoustics mainly by three models: detour-based, energetic and wave-based diffraction models. In the past, we thoroughly compared Maekawa's detour law, the uncertainty relation based diffraction method and ...

Full field vertical scanning in short coherence digital holographic microscope

Christian Depeursinge, Christophe Moser, Etienne Cuche, Frédéric Montfort

In Digital holography Microscopes (DHM) implemented in the so-called "off axis" configuration, the object and reference wave fronts are not co-planar but form an angle of a few degrees. This results into two main drawbacks. First, the contrast of the inter ...

Quantitative phase noise in a two-color low coherence Digital Holographic Microscope

Christian Depeursinge, Christophe Moser, Frédéric Montfort, Zahra Monemhaghdoust

In digital holographic microscopy (DHM), the long coherence length of laser light causes parasitic interferences due to multiple reflections in and by optical components in the optical path of the microscope and thus degrades the image quality. The parasit ...

Electro-switchable polydimethylsiloxane-based optofluidics

Andreas Vasdekis, Luciano De Sio, Marilisa Romito

We report on the fabrication and characterization of a new generation of electro-switchable optofluidic devices based on flexible substrates, combined with the extraordinary properties of reconfigurable soft-materials. A conductive polydimethylsiloxane mic ...

Single shot dual wavelength full field imaging in low coherence digital holographic microscopy

Christian Depeursinge, Christophe Moser, Frédéric Montfort, Zahra Monemhaghdoust

In off-axis digital holographic microscopy, short coherence length of the source results in an unwanted reduced field of view. A diffractive optical element (DOE) which combines two high efficiency transmission volume phase gratings holographically recorde ...

Dual wavelength full field imaging in low coherence digital holographic microscopy

Christian Depeursinge, Christophe Moser, Frédéric Montfort, Zahra Monemhaghdoust

A diffractive optical element (DOE) is presented to simultaneously manipulate the coherence plane tilt of a beam containing a plurality of discrete wavelengths. The DOE is inserted into the reference arm of an off-axis dual wavelength low coherence digital ...
