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...
PublicationsHigh-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...
PublicationsRaman 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...
PublicationsMultiple 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...
PublicationsSuperresolution 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...
PublicationsNarrow bandpass cryogenic filter for microwave measurements
An ultra-wide stopband hairpin bandpass filter with integrated nonuniform transmission lines was designed and fabricated for highly sensitive measurements at cryogenic temperatures down to millikelvin...
PublicationsAmyloids: from molecular structure to mechanical properties
Many proteins of diverse sequence, structure and function self-assemble into morphologically similar fibrillar aggregates known as amyloids. Amyloids are remarkable polymers in several respects. First...
PublicationsAmide I vibrational mode suppression in surface (SERS) and tip (TERS) enhanced Raman spectra of protein specimens
Surface- and tip-enhanced Raman spectroscopy (SERS and TERS) are modern spectroscopic techniques, which are becoming widely used and show a great potential for the structural characterisation of biological...
PublicationsRaman Spectroscopy and Imaging: Promising Optical Diagnostic Tools in Pediatrics
This review focuses on the use of Raman spectroscopy, an analytical technique based on the inelastic scattering of harmless laser light with biological tissues, as an innovative diagnostic tool in pediatrics....
PublicationsObservation of Gigawatt-Class THz Pulses from a Compact Laser-Driven Particle Accelerator
We report the observation of sub-picosecond terahertz (T-ray) pulses with energies $geq460$ $mu$J from a laser-driven ion accelerator, thus rendering the peak-power of the source higher even than that...
