Fabry-Perot Cavity Based on a Suspended-Core Fiber for Strain and Temperature Measurement
A fiber-optic Fabry–Pérot sensing structure based on the utilization of a suspended-core fiber is presented. The interferometric structure is formed when a small length of the suspendedcore fiber is...
PublicationsSelectively Deposited Silver Coatings on Gold-Capped Silicon Nanowires for Surface-Enhanced Raman Spectroscopy
Gold caps on silicon nanowires are hemispherical and only a few tens of nanometers in diameter when grown from metal catalysts by the vapor-liquid-solid growth mechanism using chemical vapor deposition....
PublicationsReconstruction of high-resolution holographic microscopic images
In in-line holographic microscopy a pinhole illuminates an object and a CCD-detector directly records the hologram in a pixel-pitch-dependent distance. A rapidly calculating exact reconstruction technique...
PublicationsImpact of fixation on in vitro cell culture lines monitored with Raman spectroscopy
Raman spectroscopy provides chemical-rich information about the composition of analytes and is a powerful tool for biological studies. With the ability to investigate specific cellular components or image...
PublicationsNegative-index materials: Two approaches for nanofabricated metamaterials
In this work we present results on the practical realization of optical negative-index metamaterials based on two different geometries for the visible and near infrared (NIR) domains. A detailed description...
PublicationsSensing properties of fiber Bragg gratings in small-core Ge-doped photonic crystal fibers
We report about fiber Bragg gratings (FBGs) inscribed in two different types of small-core Ge-doped photonic crystal fibers with a UV laser. Sensing properties of the FBGs were systematically investigated...
PublicationsMorphology-sensitive Raman modes of the malaria pigment hemozoin
Resonance Raman spectroscopy was applied for investigating the malaria pigment hemozoin, which is an important target structure of antimalarial drugs. Morphology-sensitive low wavenumber modes of hemozoin...
PublicationsUV cross-linking of unmodified DNA on glass surfaces
The performance of DNA microarrays strongly depends on their surface properties. Furthermore, the immobilization method of the capture molecules is of importance for the efficiency of the microarray in...
PublicationsArF laser induced pulse absorption in fused silica (type III): Modeling the fluence and repetition rate dependence
At 193 nm, weak stationary bulk absorption coefficients astat in standard and experimental grade fused silica (type III) are measured in dependence on the laser fluence H and repetition rate f. The samples...
PublicationsRaman and CARS microspectroscopy of cells and tissues
Raman spectroscopy has been recognized to be a powerful tool to study cells and tissues because the method provides molecular information without external markers such as stains or radioactive labels....
