A 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...
PublikationenAn 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...
PublikationenUnderdamped 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...
PublikationenInner 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...
PublikationenMicrostructured 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...
PublikationenIn situ excimer laser irradiation as cleaning tool for solid phase epitaxy of laser crystallized polycrystalline silicon thin films
This study demonstrates an innovative approach to clean a polycrystalline seed layer surface for solid phase epitaxy of amorphous silicon (a-Si). The excimer laser cleaning (ELC) makes use of in situ excimer...
PublikationenFörster Resonance Energy Transfer in Poly(methyl methacrylates) Copolymers Bearing Donor-Acceptor 1,3-Thiazole Dyes
The Förster resonance energy transfer (FRET) properties in poly(methyl methacrylate) copolymers containing 2-(pyridine-2-yl) thiazole dyes were studied upon systematic variation of the donor-to-acceptor...
PublikationenMonitoring the chemistry of self-healing by vibrational spectroscopy – current state and perspectives
Self-healing materials are designed to heal damage caused by, for example, mechanical stress or corrosion such that the original functionality of the material is at least partially restored. Thus, self-healing...
PublikationenAutomatic Identification of Novel Bacteria using Raman Spectroscopy and Gaussian Processes
Raman spectroscopy is successfully used for the reliable classification of complex biological samples. Much effort concentrates on the accurate prediction of known categories for highly relevant tasks...
PublikationenQuantification of the inorganic phase of the pelagic aggregates from an iron contaminated lake by means of Raman spectroscopy
A semi-quantitative investigation of the inorganic phase of pelagic, iron-rich aggregates (iron snow, IS) formed in an iron polluted aquatic environment was performed by means of Raman spectroscopy. IS...
