The average transmittance (Tavg%) and optical energy gap (Eg) increased rapidly with increasing O2 flow. The resistivity significantly increased with increasing O2 flow for annealing temperature at 200°C, however the resistivity did not change with the O2 flow for the annealing temperature at 400°C. Hall mobility reached the highest value of 11.18 cm2V−1sec− when the O2 flow is at 5 sccm and the carrier...
Summary The monitoring of pollution in the environment is of increasing importance. Atmospheric pollutants can generally be detected using Fourier Transform Infrared Spectroscopy (FTIR), but automatic identification of these pollutants from their spectrum is not trivial. It is often desirable to not only identifi pollutants but also to estimate their concentration, so that it is possible to determine...
We investigate the influence of taper geometry in Er/Yb co-doped fiber (EYDF) strain sensors using tunable abrupt-tapered Mach-Zehnder interferometers (AT-MZI). It was found that the sensitivity of the strain sensor can be enhanced by reducing both the waist diameters of, and the span between the two abrupt tapers. For strains under 0.2% in AT-MZIs with a consistent span of 10 mm, the strain-induced...
