Cell classification with low-resolution Raman spectroscopy (LRRS)
The identification of individual eukaryotic and prokaryotic cells is the backbone of clinical pathology and provides crucial information about the genesis and progression of a disease. While most commonly...
PublicationsDirect absorption measurements in thin rods and optical fibers
We report on the first realization of direct absorption measurements in thin rods and optical fibers using the laser induced deflection (LID) technique. Typically, along the fiber processing chain more...
PublicationsIdentification of zero density of states domains in band gap fibers using a single binary function
Here we introduce a new calculation method to find the domains of zero density of states for photonic band gap guiding fibers consisting of arrays of high refractive index strands in a low refractive index...
PublicationsSingle mode criterion – a benchmark figure to optimize the performance of nonlinear fibers
Optical fibers with sub-wavelength cores are promising systems for efficient nonlinear light generation. Here we reveal that the single-mode criterion represents a convenient design tool to optimize the...
PublicationsOptimization of Raman-Spectrum Baseline Correction in Biological Application
In the last decade Raman-spectroscopy has become an invaluable tool for biomedical diagnostics. However, a manual rating of the subtle spectral differences between normal and abnormal disease states is...
PublicationsAutomatization of spike correction in Raman spectra of biological samples
Raman spectroscopy as a technique has high potential for biological applications, e.g. cell and tissue analysis. In these applications, large data sets are normally recorded which require automated analysis....
PublicationsOptical properties of silicon nanowires fabricated by environment-friendly chemistry
Silicon nanowires (SiNWs) were fabricated by metal-assisted chemical etching (MACE) where hydrofluoric acid (HF), which is typically used in this method, was changed into ammonium fluoride (NH4F). The...
PublicationsComparing Raman and fluorescence lifetime spectroscopy from human atherosclerotic lesions using a bimodal probe
Fluorescence lifetime imaging (FLIm) and Raman spec-troscopy are two promising methods to support morpho-logical intravascular imaging techniques with chemical contrast. Both approaches are complementary...
PublicationsMultimodal nonlinear microscopy of head and neck carcinoma – toward surgery assisting frozen section analysis
Background. Treatment of early cancer stages is deeply connected to a good prognosis, a moderate reduction of the quality oflife, and comparably low treatment costs. Methods. Head and neck squamous cell...
PublicationsAluminum Doped Zinc Oxide Layers by Atomic Layer Deposition and Magnetron Sputtering: Formation and Comparison of Optoelectronic Properties
Thin films of aluminum-doped zinc oxide (AZO) were prepared using magnetron sputtering and atomic layer deposition (ALD) techniques. Atomic force microscopy (AFM) studies of AZO films surface morphology...
