Time-Tagged Multiplexing of Serially Biased Superconducting Nanowire Single-Photon Detectors

We present a concept for a time-tagged multiplexed readout of several SNSPD detector elements for ultra-short pulsed laser applications. The detector elements were coupled in an array by a superconducting...

Evidence for SERRS Enhancement in the Spectra of Ruthenium Dye-Metal Nanoparticle Conjugates

Metal-molecule interfaces bare a high potential for application in various fields of chemistry as the features and functions of metal nanostructures can be modified and – to a certain degree - be extended...

Simulation of symetrically doped silicon nanowire solar cells

Silicon nanowire solar cells were simulated using the Silvaco TCAD software kit. For optimization of speed the simulations were performed in cylinder coordinates with cylindrical symmetry. Symmetric doping...

Influence of the Contacting Scheme in Simulations of Radial Silicon Nanowire Solar Cells

Recent advances in ultrafast time-resolved chirality measurements: perspective and outlook

Observing chirality changes as they occur is an important topic of research. It provides information that deepens the understanding of biomolecular configuration and conformation under environmental changes....

Light Propagation in Tapered Optical Fibers: Spation Light Confinement and Generation of Plasmonic Waves

Light propagation in optical waveguides is fundamentally different from free space propagation since light spreading by diffraction is avoided. The light is confined to modes which stay constant in shape...

High-resolution imaging of autofluorescent particles within drusen using structured illumination microscopy

Purpose: Autofluorescent (AF) material within drusen has rarely been described and there is little knowledge about origin and formation of these particles. Drusen formation is still a relatively unknown...

Raman Spectroscopy – A Powerful Approach Towards Labelfree Biomedical Diagnostic

In this contribution we review our recent results on Raman approaches to address important biomedical questions. Raman based methods are ideal tools for medical and life science research: Raman measures...

Multiple Core-Shell Silicon Nanowire-Based Heterojunction Solar Cells

Silicon nanowire based solar cells received increasing attention due to their enhanced light harvesting properties and the potential to use low-cost materials to produce solar cells comparable with those...

Superresolution Multidimensional Imaging with Structured Illumination Microscopy

The resolution of an optical microscope is fundamentally limited by diffraction. In a conventional wide-field fluorescence microscope, the resolution limit is around 200nm. However, modern super-resolution...
