Viscosity of fluorine-doped silica glasses
The viscous behavior of fluorine-doped synthetic silica is studied using collapsing experiments with different fluorine-doped tubes on a modified chemical vapor deposition(MCVD) lathe. The principles,...
PublicationsFiber-integrated Absorption Spectroscopy Using Liquid-filled Nanobore Optical Fibers
Absorption spectroscopy represents one highly relevant approach in current analytics for noninvasively characterize liquid analytes. Here we present the concept of waveguide-integrated absorption spectroscopy...
PublicationsAnomalous transparency in photonic crystals and its application to point-by-point grating inscription in photonic crystal fibers
It is common belief that photonic crystals behave similarly to isotropic and transparent media only when their feature sizes are much smaller than the wavelength of light. Here, we counter that belief...
PublicationsPolarization Evolution in Antiresonant Hollow Core Fibers
Understanding polarization in waveguides is of fundamental importance for any photonic device and is particular relevant within the scope of fiber optics. Here we investigate the dependence of the geometry-induced...
PublicationsPlasmon response evaluation based on image-derived arbitrary nanostructures
The optical response of realistic 3D plasmonic substrates composed of randomly shaped particles of different size and interparticle distance distributions in addition of nanometer scale surface roughness...
PublicationsSolid-Core Fiber Spectral Broadening at Its Limits
Broadband optical spectra are employed in ultrafast time-resolved studies, seeding of tunable parametric amplifiers, and selectively addressing transitions in absorption spectroscopy. A strong extension...
PublicationsRobustness of light-transport processes to bending deformations in graded-index multimode waveguides
Light transport through a multimode optical waveguide undergoes changes when subjected to bending deformations. We show that optical waveguides with a perfectly parabolic refractive index profile are almost...
PublicationsA healing ionomer crosslinked by a bis-bidentate halogen bond linker: a route to hard and healable coatings
In this work we present the first incorporation of bis-bidentate halogen bond linkers into an organic healing ionomer system resulting in the formation of crosslinked supramolecular networks. The obtained...
PublicationsCharacterization of nonlinear optical crystal absorption
A simplified absolute calibration for the photothermal laser-induced deflection technique is introduced and applied to characterize different nonlinear optical crystals at common diode pumped solid state...
PublicationsReconstitution of immune cell interactions in free-standing membranes
The spatiotemporal regulation of signalling proteins at the contacts formed between immune cells and their targets determines how and when immune responses begin and end. It is important, therefore, to...
