Light-triggered CO release from nanoporous non-wovens
The water insoluble and photoactive CO releasing molecule dimanganese decacarbonyl (CORM-1) has been non-covalently embedded into poly(L-lactide-co-D/L-lactide) nanofibers via electrospinning to enable...
PublicationsFormation of self-trapping waveguides in bulk PMMA media doped with Phenanthrenequinone
Experimental and theoretical investigations of light self-trapping waveguides in a bulk polymeric medium based on polymethylmethacrylate (PMMA) with photosensitive phenanthrenequinone (PQ)-molecules are...
PublicationsRaman fiber probes – Current development and future trends
Raman spectroscopy has been proven to be a powerful bio-diagnostically tool. With this technique several biomedical questions were addressed, e.g. tumor detection, cell differentiation, the in-vivo arteriosclerotic...
PublicationsAccumulating advantages, reducing limitations: Multimodal nonlinear imaging in biomedical sciences – the synergy of multiple contrast mechanisms
Multimodal nonlinear microscopy has matured during the past decades to one of the key imaging modalities in life science and biomedicine due to its unique capabilities of label-free visualization of tissue...
PublicationsTuning of Spectral and Angular Distribution of Scattering from Single Gold Nanoparticles by Subwavelength Interference Layers
Localized surface plasmon resonance (LSPR) as the resonant oscillation of conduction electrons in metal nanostructures upon light irradiation is widely used for sensing as well as nanoscale manipulation....
PublicationsNanotechnology enhanced solar cells prepared on laser-crystallized polycrystalline thin films (< 10 µm)
It is shown in this paper that indeed silicon nanotechnology can significantly improve the performance of solar cells made on low-cost materials like polycrystalline silicon (pc-Si) thin films deposited...
PublicationsTapered large-core 976 nm Yb-doped fiber laser with 10 W output power
We report on a tapered large-core Yb fiber laser operating at 976 nm emission wavelength. It was realized using a high-numerical aperture large-core fiber with 126 µm core diameter, which was fabricated...
PublicationsTEM analysis of Si thin films prepared by diode laser induced solid phase epitaxy at high temperatures
The solid phase crystallization of amorphous silicon thin films deposited on -oriented wafers at high temperatures was investigated. The films were heated up by diode laser irradiation for some milliseconds...
PublicationsThe influence of deposition parameters on Ti/Pt film growth by confocal sputtering and the temperature dependent resistance behavior using SiOx and Al2O3 substrates
This paper presents the influence of sputtering power and pressure on microstructural growth and morphology of Ti/Pt films and their electrical properties for possible applications in thin film thermal...
PublicationsEffect of the silica bridge thickness of suspended core fiber on the acousto-optic modulation of fiber Bragg gratings
The acousto-optic modulation of Bragg gratings is investigated for suspended-core fibers. The bridge thickness is increased and the mechanical and the grating properties are simulated. An increase of the...
