Investigation of intermodal interference of LP01 and LP11 modes in the liquid-core optical fiber for temperature measurements

The intermodal interference of the LP01 and LP11 modes and determination of the equalization wavelength in the liquid-core optical fiber is presented. Theoretically was described the weakly guiding optical...

Femtosecond Coherence Spectroscopic Study of the Onset of Chemical Denaturation of Myoglobin upon Addition of Minor Amounts of Urea

The interaction of urea with myoglobin, as a benchmark system for heme-containing proteins, is studied via femtosecond coherence spectroscopy. The work focuses on the effect of urea on the appearance of...

Temperature influence on the photodarkening kinetics in Yb-doped silica fibers

We report on the characterization of photodarkening (PD) kinetics of Yb-doped fiber samples in a wide temperature range from 77 to 773K and with respect to different Yb2O3 concentrations from 0.09 up to...

Optical refractometer based on large-core air-clad photonic crystal fibers

A large-core air-clad photonic crystal fiber-based sensing structure is described, which is sensitive to refractive index. The sensing head is based on multimodal interference, and relies on a single-mode/large-core...

The Direct Writing of Plasmonic Gold Nanostructures via Electron Beam Induced Deposition

Correlating internal stresses, electrical activity and defect structure on the micrometer scale in EFG silicon ribbons

In the present paper, we study the influence of defects through their stress fields on the electrical activity and residual stress states of as-grown edge-defined film-feed (EFG) multicrystalline silicon...

Catalyst-free functionalization for versatile modification of nonoxidized silicon structures

Here, we report on a simple, catalyst-free route for obtaining highly versatile subsequent functionalization on Si nanowires and Si(111) substrates. The versatility of this approach allows subsequent functionalization...

Chemical and Optical Characterisation of Atomic Layer Deposition Aluminium doped ZnO films for Photovoltaics by Glow Discharge Optical Emission Spectrometry

Aluminium doped ZnO (AZO) alloy films produced by atomic layer deposition (ALD) are analysed by glow discharge optical emission spectrometry (GD-OES). A measurement procedure is established, to determine...

Protonation effects on the resonance Raman properties of a novel (terpyridine)Ru(4H-imidazole) complex: An experimental and theoretical case study

The optically active states in a novel Ruthenium-terpyridine complex displaying an unusually broad and redshifted absorption in the visible range are investigated experimentally and theoretically. While...

Growth of doped silicon nanowires by pulsed laser deposition and their analysis by electron beam induced current imaging

Doped silicon nanowires (NWs) were epitaxially grown on silicon substrates by pulsed laser deposition following a vapour–liquid–solid process, in which dopants together with silicon atoms were introduced...
