All-fiber time-delay spectrometer based on an array of fiber Bragg gratings
We have investigated the possibility to use a step-chirped fiber Bragg grating array for a time-delay-spectrometer. This concept allows a simultaneous spectral and temporal characterization of pulsed light...
PublicationsObservation of Discrete, Vortex Light Bullets
We report the first experimental observation of Vortex Light Bullets which are discrete, spatiotemporal, solitary waves with orbital angular momentum. We analyze conditions for their existence and investigate...
PublicationsSQUID-based absolute vector magnetometer
The aim of this work is to measure the absolute Earth’s magnetic field components in a mobile operation with high precision. Due to their periodic voltage-flux characteristics, SQUIDs are not able to...
PublicationsPlasmonics – principles and applications
Plasmonics is a field of research investigating electromagnetic modes coupled to metal-dielectric interfaces and metal nanostructures. These modes are spatially confided bellow the wavelength of the light...
PublicationsMicrowave characterisation of nanomechanical resonator
There are a variety of methods for measuring the characteristics of nanoscale resonators. In either of these methods it is necessary to transform the mechanical vibrations of nanoscale mechanical resonator...
PublicationsUnusual Raman spectra of para-nitroaniline by sequential Fermi resonances
In this communication, we report the unusual Raman spectra of para-nitroaniline (PNA) by sequential Fermi resonances. The combinational mode 1292 cm-1 in the experimental Raman spectrum indirectly gains...
PublicationsInsight into vibration mode-resolved plasmon enhanced Raman optical activity
Vibration mode-resolved plasmon enhanced Raman optical activities (PE-ROA) are investigated experimentally and theoretically. It is found that the profile of PE-ROA is significantly different from that...
PublicationsRaman-Spectroscopy Based Cell Identification on a Microhole Array Chip
Circulating tumor cells (CTCs) from blood of cancer patients are valuable prognostic markers and enable monitoring responses to therapy. The extremely low number of CTCs makes their isolation and characterization...
PublicationsATR-FTIR and Raman spectroscopy of primary and permanent teeth
BACKGROUND: Valuable structural and chemical properties can be obtained for dentin and enamel by vibrational spectroscopy. A better understanding of structural and chemical changes in deciduous dentition...
PublicationsPhenalenone-type phytoalexins mediate resistance of banana plants (Musa spp.) to the burrowing nematode Radopholus similis
The global yield of bananas—one of the most important food crops—is severely hampered by parasites, such as nematodes, which cause yield losses up to 75%. Plant–nematode interactions of two banana...
