Efficient Adaptive Step Size Method for the Simulation of Supercontinuum Generation in Optical Fibers

The use of an adaptive step size selection significantly reduces the computational effort for the numerical solution of the generalized nonlinear Schrödinger equation (GNLSE). The most commonly employed...

Photochemical Fate: The First Step Determines Efficiency of H-2 Formation with a Supramolecular Photocatalyst

The color of the incident light determines the efficiency of the hydrogen evolution mediated by a supramolecular photocatalyst. This finding demonstrates the importance of the Franck–Condon point in...

Silicon nanowires terminated with methyl functionalities exhibit stronger Si-C bonds than equivalent 2D surfaces

Silicon nanowires (Si NWs) terminated with methyl functionalities exhibit higher oxidation resistance under ambient conditions than equivalent 2D Si(100) and 2D Si(111) surfaces having similar or 10–20%...

Realization of Vertical and Zigzag Single Crystalline Silicon Nanowire Architectures

Silicon nanowire (SiNW) ensembles with vertical and zigzag architectures have been realized using wet chemical etching of bulk silicon wafers (p-Si(111) and p-Si(100)) with a mask of silver nanoparticles...

A New Four Bit Magnetic Domain Wall Based Multiturn Counter

A multiturn counter is proposed which is based on domain wall movement. This sensor has a true-power-on functionality and works gear-less. Due to the new design of the multiturn, the drawbacks of the former...

Limits of light guidance in optical nanofibers

Optical switch based on a fluid-filled photonic crystal fiber Bragg grating

We report the implementation of an in-fiber optical switch by means of filling a fluid into the air holes of a photonic crystal fiber with a fiber Bragg grating. Such a switch can turn on/off light transmission...

Measuring the spatial polarization distribution of multimode beams emerging from passive step-index large-mode-area fibers

We measure the polarization state of each guided transversal mode propagating in step-index large-mode-area fibers (V ≈ 4) using a correlation-filter based measurement technique in combination with a...

Experimental Comparison of Fundamental Mode Content in Er:Yb-Codoped LMA Fibers With Multifilament- and Pedestal-Design Cores

Prediction of Electron Densities, the Respective Laplacians, and Ellipticities in Bond-Critical Points of Phenyl-CH-Bonds via Linear Relations to Parameters of Inherently Localized CD Stretching Vibrations and H-1 NMR-Shifts

Electron densities ρ, the respective laplacians ▽2ρ, and ellipticities ϵ in bond-critical points (BCPs) are reactivity-determining characteristics according to the theory of atoms in molecules. These...
