Topological interface states in one-dimensional electronic and photonic systems are currently intensively investigated. We demonstrate the coupling of topologically confined states: By concatenation of three substructures, where the outer embedding structures have opposite signs of reflection phases to the embedded structure, we …

We investigate coherent perfect absorption in a microcavity with C60 as an organic absorbing material. The experiment consists of a two-beam setup of counterpropagating laser beams incident on a single sample from opposite sides, resulting in two counterpropagating outputs consisting of the …

Öffentlichkeit und Politik müssen häufig den Eindruck gewinnen, dass Wirtschaftswissenschaftler bei zentralen wirtschaftspolitischen Fragen keine Einigkeit erzielen können. Dies gilt nicht zuletzt für die Umsetzung der Energiewende. Dieser Beitrag nutzt die öff entlich zugänglichen Stellungnahmen einschlägiger Forschungsinstitute, um durch die Identifikation von …

The use of deployable fibre-bundles plays an increasing role in the design of future Multi-Object-Spectrographs (MOS). Within a research and development project for "Enabling Technologies for the E-ELT", various miniaturized, fibrebundles were designed, built and tested for their suitability for a proposed …

We describe our development of heat-resistant solar cells made by depositing the interference filter pigment Solarflair on \nthe surface of silicon and compound semiconductor solar cells. The coating is designed to reflect long wavelength \ncomponents of solar radiation while admitting shorter wavelength …
