High Birefringence Triangular Optical Nanowire in Suspended-Core Fiber for Temperature Sensing
Triangular optical nanowires that present a high birefringence and a very strong confinement are fabricated. The nanowires are created by tapering suspended-core fiber down to core diameters below 1 μm....
PublikationenSuperresolution Imaging of Dynamic MreB Filaments in B. subtilis—A Multiple-Motor-Driven Transport?
The cytoskeletal protein MreB is an essential component of the bacterial cell-shape generation system. Using a superresolution variant of total internal reflection microscopy with structured illumination,...
PublikationenReal-time image processing for label-free enrichment of Actinobacteria cultivated in picolitre droplets
The majority of today’s antimicrobial therapeutics is derived from secondary metabolites produced by Actinobacteria. While it is generally assumed that less than 1% of Actinobacteria species from soil...
PublikationenExperimental setup for investigating silicon solid phase crystallization at high temperatures
An experimental setup is presented to measure and interpret the solid phase crystallization of amorphous silicon thin films on glass at very high temperatures of about 800°C. Molybdenum-SiO2-silicon film...
PublikationenMid-infrared supercontinuum generation in As2S3-silica “nano-spike” step-index waveguide
Efficient generation of a broad-band mid-infrared supercontinuum spectrum is reported in an arsenic trisulphide waveguide embedded in silica. A chalcogenide “nano-spike”, designed to transform the...
PublikationenAn all-fiber Raman laser for cylindrical vector beam generation
We demonstrate a compact Raman all-fiber oscillator for cylindrical vector beam generation. The laser is based on a strongly guiding passive fiber with two fiber Bragg gratings inscribed in it, which separates...
PublikationenRaman investigations of Upper Cretaceous phosphorite and black shale from Safaga District, Red Sea, Egypt
The mineral composition of the Upper Cretaceous Duwi phosphorite deposits and underlying Quseir Variegated Shale from Safaga district, Red Sea Range, Egypt, was investigated by dispersive and Fourier transformed...
PublikationenMagneto-optical analysis of stripe elements embedded in a synthetic antiferromagnet
Domain structures and the magnetic reversals of micron stripe patterns embedded in a weakly antiferromagnetically exchange coupled Co90Fe10/Ru/Co90Fe10 trilayer were investigated. Patterning was achieved...
PublikationenUncooled thermocouple air-bridge structure for a THz imaging system
We have developed an air-bridge structure supporting a thermocouple-based conducting strip, which acts as both a terminating resistance of an antenna and temperature sensor. The fabrication of the 30 µm...
PublikationenMeasuring conditions for second order X-ray Bragg-spectrometry
The KL2,3 (alpha)12-lines of 19K, the L3M4,5 (alpha)12-lines of 48Cd, and the M5N6,7 (alpha)12-lines of 92U are lines of comparable energy in the region of approximately 3 keV. In none of these cases were...
