Single Crystal Ge Core Fiber Produced via Pressure Assisted Melt Filling and CO2 Laser Crystallization

We present a simple two step process for the fabrication of single crystal germanium core fibers. Germanium is deposited into a capillary in a highly polycrystalline state using the pressure assisted melt...

Science of Light Scattering of Solvent Undergoes Evolution: Improved Spectrophotometric Measurement Rehabilitates Einstein-Smoluchowski Equation

Fine-tuning of the optical properties of hollow-core light cages using dielectric nanofilms

Here, we show that the optical properties of direct-laser-written on-chip hollow-core waveguides—so-called light cages—can be controlled to a very high degree by dielectric nanofilms. Using low-temperature...

Essentials of resonance-enhanced soliton-based supercontinuum generation

Supercontinuum generation is a key process for nonlinear tailored light generation and strongly depends on the dispersion of the underlying waveguide. Here we reveal the nonlinear dynamics of soliton-based...

Tailoring modulation instabilities and four-wave mixing in dispersion-managed composite liquid-core fibers

We show that the ultrafast nonlinear dynamics in supercontinuum generation can be tailored via mixture-based liquid core fibers. Samples containing mixtures of inorganic solvents allow changing dispersion...

Convectionless directional solidification in an extremely confined sample geometry

A method for the investigation of directional solidification in cylindrical metallic samples with diameters of 2 µ m and lengths of 5 cm, embedded in glass capillaries is presented. We estimate the...

Novel approach for high-performance optical fibers: multiple-doped silica powders with plasma-enhanced processes

This paper presents an innovative one-step doping approach for the preparation of Al-Yb co-doped silica glasses for fiber preforms. Today, fiber-lasers are of great interest in industry due to highest...

Hybrid sensor based on microstructured hollow core fiber for simultaneous measurement of strain and temperature

A hybrid sensor based on microstructured hollow core fiber is proposed for the simultaneous measurement of strain and temperature. The fiber, consisting of four silica capillaries with wall thickness of...

Microarray-based detection of resistance genes in coagulase-negative staphylococci isolated from cattle and buffalo with mastitis in Egypt

Locally Condensed Water as a Solution for In Situ Wet Corrosion Electron Microscopy

In microstructural corrosion studies, knowledge on the initiation of corrosion on an nm-scale is lacking. In situ transmission electron microscope (TEM) studies can elucidate where/how the corrosion starts,...
