The 20th International Conference on Optical Fibre Sensors, OFS-20
Welcome to our special issue on fibre optic sensors. Fibre optic sensors were first suggested in the patent literature in the mid 1960s as an innovative means for making measurements. This proposed a surface...
PublicationsStructural analysis of the antimalarial drug halofantrine by means of Raman spectroscopy and density functional theory calculations
The structure of the antimalarial drug halofantrine is analyzed by means of density functional theory (DFT) calculations, IR, and Raman spectroscopy. Strong, selective enhancements of the Raman bands of...
PublicationsPulse stretcher with variable pulse length for excimer laser applications
Excimer laser systems are often combined with pulse stretchers, e.g., in lithography and Raman spectroscopy to reduce pulse peak intensities. We developed a pulse stretcher which is suited especially for...
PublicationsHot-electron effect in PdAu thin-film resistors with attached cooling fins
The sensitivity of superconducting electronics operated in the sub-Kelvin temperature range is usually limited by the hot-electron effect. Here, an increased thermal resistance due to a weakened electron–phonon...
PublicationsPolarization mode preservation in elliptical index tailored optical fibers for apertureless scanning near-field optical microscopy
We report on the development of elliptical, index tailored optical fibers for higher-order mode preservation for fiber-based, apertureless, internally illuminated scanning near-field optical microscopy...
PublicationsStress and doping uniformity of laser crystallized amorphous silicon in thin film silicon solar cells
Simultaneous and locally resolved determination of the mechanical stress variation and the free hole concentration using Raman spectroscopy is demonstrated in laser crystallized amorphous silicon layers....
PublicationsControlled initialization of superconducting pi-phaseshifters and possible applications
The rapid single-flux quantum electronics (RSFQ) is a superconducting, naturally digital circuit family which is currently close to being commercially applied. RSFQ is outstanding because of its very low...
PublicationsRefractive index tip sensor based on Fabry-Perot cavities formed by a suspended core fibre
A Fabry-Perot refractometer based on the suspended core fibre is presented. The Fabry-Perot cavities are formed by a section of suspended core fibre between conventional single-mode fibres. This miniature...
PublicationsWeak continuous monitoring of a flux qubit using coplanar waveguide resonator
We study a flux qubit in a coplanar waveguide resonator by measuring transmission through the system. In our system with the flux qubit decoupled galvanically from the resonator, the intermediate coupling...
PublicationsIntracellular ion monitoring using a gold-core polymer-shell nanosensor architecture
In this study, we describe the design of new ratiometric fluorescent nanosensors, whose architecture is based on a gold core surrounded by a poly(vinyl alcohol)–polyacetal shell. To the gold core, indicator...
