Inorganic Salts In Atmospheric Particulate Matter: Raman Spectroscopy As An Analytical Tool
Atmospheric particulate matter is composed of inorganic and organic components of natural and anthropogenic origin. Wind-transport is probably the most important process responsible for the emission of...
PublicationsUnambiguous position and orientation tracking using a rotating magnet
We present a measurement system for magnetic position and orientation tracking. It uses a rotating magnet as transmitter and a three-axis magnetic field sensor to measure the magnetic field ellipse produced...
PublicationsOptical spectroscopy of photovoltaic systems based on low-bandgap polymers
We report on the optical characterization of a low-bandgap thieno[3,4-b]pyrazine phenylenevinylene copolymer. Individual layers on quartz and Si substrates as well as layered structures on ITO covered...
PublicationsInkjet printed silver back contacts for flexible amorphous silicon thin-film solar cells on glass fiber fabrics
The preparation of inkjet printed silver back contacts for flexible amorphous silicon thin-film solar cells on textile glass fiber fabrics is presented. The silver tracks were printed onto glass fiber...
PublicationsSolar spectral conversion for improving the photosynthetic activity in algae reactors
Sustainable biomass production is expected to be one of the major supporting pillars for future energy supply, as well as for renewable material provision. Algal beds represent an exciting resource for...
PublicationsA gold-nanotip optical fiber for plasmon-enhanced near-field detection
A wet-chemical etching and mechanical cleaving technique is used to fabricate gold nanotips attached to tapered optical fibers. Localized surface plasmon resonances (tunable from 500 to 850 nm by varying...
PublicationsAn arbitrary waveform generator for fast high sensitive measurements
The new high functionality high speed and easy programming arbitrary waveform generator (AWG) was designed and implemented for high sensitive superconducting flux qubit measurements. The generator provides...
PublicationsUnderdamped Josephson junction as a switching current detector
We demonstrate the narrow switching distribution of an underdamped Josephson junction from the zero to the finite voltage state at millikelvin temperatures. We argue that such junctions can be used as...
PublicationsInner cladding microstructuration based on symmetry reduction for improvement of singlemode robustness in VLMA fiber
Very large mode area, active optical fibers with a low high order mode content in the actively doped core region were designed by removing the inner cladding symmetry. The relevance of the numerical approach...
PublicationsMicrostructured Optical Fibers from Silica Preforms by Free Form Laser Drilling
We describe a laser drilling technology suitable for the creation of preforms for microstructured optical fibers from solid silica rods. This technology enables the realization of fiber designs that can...
