Anisotropic Two- And Four-wave Mixing In Planar Litao3:ti:fe Optical Waveguides
, 2015 We report on anisotropic wave mixing in planar iron-doped titanium-indiffused LiTaO3 waveguides. The diffusion of titanium in Y-cut LiTaO3 is investigated for different temperatures and diffusion times, yielding the diffusion constant.

Planar Solid‐State Nanopores Toward Scalable Nanofluidic Integration Based on CMOS Technology
Advanced Engineering Materials, EarlyView.We present a scalable silicon‐based fabrication strategy for planar solid‐state nanopores to enable their integration with complex nanofluidic systems. Prototype devices demonstrate normal voltage‐current characteristics, good noise performance, and appreciable streaming currents. Our CMOS‐compatible fabrication process offers precise geometric control

OPTICAL CONSTANTS AND THEIR MEASUREMENT [PDF]
Le Journal de Physique Colloques, 1977 A description of the optical properties of solids, especially metals, in terms of a dielectric function is outlined, along with some of its limitations. Methods of deriving this function from measurements are outlined as well. Errors due to sample preparation, rather than measurement errors, are emphasized.

Comparative signal-to-noise analysis of fibre-optic based optical coherence tomography systems
, 2005 Several optical coherence tomography ( OCT) systems are proposed using optical. fibre components and based around Fizeau sensing interferometers. The theoretical signal- to- noise ratio ( SNR) is calculated for each of the proposed configurations ...

Advanced Engineering Materials, EarlyView.This study demonstrates an efficient recycling route for out‐of‐spec AlSi10Mg atomized powders through compaction and arc remelting followed by suction casting. By correlating compaction load, cooling rate, and resulting microstructure, we show that intermediate pressures (50–80 kN) and rapid cooling refine dendrites, reduce porosity, and enhance ...
