Invited Article: Comparison of hyperspectral coherent Raman scattering microscopies for biomedical applications
Raman scattering based imaging represents a very powerful optical tool for biomedical diagnostics. Different Raman signatures obtained by distinct tissue structures and disease induced changes provoke...
PublicationsNumerical analysis of a folded superconducting coaxial shield for cryogenic current comparators
This paper presents a new shield configuration for cryogenic current comparators (CCCs), namely the folded coaxial geometry. An analytical model describing its shielding performance is developed first,...
PublicationsHermetic sealing of MEMS including lateral feedthroughs and room-temperature anodic bonding
This paper reports on a method for hermetic sensor housing including lateral feedthroughs and room-temperature anodic bonding. The planarisation of the lateral feedthroughs, essential for the purpose of...
PublicationsMulti-watt, multi-octave, mid-infrared femtosecond source
Spectroscopy in the wavelength range from 2 to 11 mu m (900 to 5000 cm(-1)) implies a multitude of applications in fundamental physics, chemistry, as well as environmental and life sciences. The related...
PublicationsPhotodarkening in Yb-doped silica fibers – mitigation by co-doping and thermal effects
Photodarkening in rare-earth doped fibers has been subject of intense research over the last decade as the main issue limiting high power performance and long-term stability of fiber lasers. Regarding...
PublicationsUnderwater operation of a full tensor SQUID gradiometer system
For the first time a mobile underwater Full Tensor Magnetic Gradiometer (FTMG) system based on low-Tc Superconducting Quantum Interference Devices (SQUIDs) has been deployed in order to scan the seafloor...
PublicationsOn the heading error of optically pumped magnetometers operated in Earth magnetic field
In the context of atomic magnetometers the term “heading error” summarizes any falsification of the measured magnetic-field strength in dependence on the orientation of the pump beam direction with...
PublicationsNanotrimer enhanced optical fiber tips implemented by electron beam lithography
Here we present a novel fabrication approach that allows implementing sophisticated planar nanostructures with deep subwavelength dimensions on fiber end faces by electron beam lithography. Specifically...
PublicationsStochasticity of domain wall pinning in curved ferromagnetic nanowires investigated by high-resolution Kerr microscopy
The stochasticity of magnetic domain wall positioning after applying rotating magnetic fields to polygonal ferromagnetic nanowire-type magnetic field sensor structures is investigated. High-resolution...
PublicationsSurface enhanced Raman spectroscopy‐detection of the uptake of mannose‐modified nanoparticles by macrophages in vitro: A model for detection of vulnerable atherosclerotic plaques
Atherosclerosis is a process of thickening and stiffening of the arterial walls through the accumulation of lipids and fibrotic material, as a consequence of aging and unhealthy life style. However, not...
