Carbon chloride-core fibers for soliton mediated supercontinuum generation

We report on soliton-fission mediated infrared supercontinuum generation in liquid core step-index fibers using highly transparent carbon chlorides (CCl4, C2Cl4). By developing models for the refractive...

An “in-fiber” Whispering-Gallery-Mode bi-sphere resonator, sensitive to nanometric displacements

A double-cavity, Whispering-Gallery-Mode (WGM) resonator, composed of two polystyrene microspheres, is formed inside the capillary of a microstructured optical fiber. The spectra are compared with the...

Fabrication of self-assembled spherical Gold Particles by pulsed UV Laser Treatment

We report on the fabrication of spherical Au spheres by pulsed laser treatment using a KrF excimer laser (248 nm, 25 ns) under ambient conditions as a fast and high throughput fabri-cation technique. The...

Cryogenic time domain multiplexer based on SQUID arrays and superconducting/normal conducting switches

Analysis of basidiomycete pigments in situ by Raman spectroscopy

Basidiomycetes, i.e., mushroom-type fungi, are known to produce pigments in response to environmental impacts. As anti-oxidants with a high level of unsaturation, these compounds can neutralize highly...

Coexistence of distinct intramolecular electron transfer pathways in polyoxometalate based molecular triads

Polyoxometalate (POM)-associated charge-separated states, formed by photoinduced oxidation of a covalently attached photosensitizer and reduction of the POM, have attracted much attention due to the remarkable...

Detection and characterization of early plaque formations by Raman probe spectroscopy and optical coherence tomography: an in vivo study on a rabbit model

Intravascular imaging techniques provide detailed specification about plaque appearance and morphology, but cannot deliver information about the biochemical composition of atherosclerotic plaques. As the...

Synthesis of shape-anisotropic nanoparticles and their application

Localized Surface Plasmon Resonance (LSPR) is a characteristic effect visible for different metal nanoparticles, like gold, silver, platinum or palladium particles. This effect is based on the excitation...

Super-resolution fluorescence microscopy studies of human immunodeficiency virus

Super-resolution fluorescence microscopy combines the ability to observe biological processes beyond the diffraction limit of conventional light microscopy with all advantages of the fluorescence readout...

Phosphatase exclusion- and aggregation-based receptor triggering cooperate to broaden FcεR1 reactivity
