A 3-dimensional physical model was developed to relate the wavelength shifts resulting from temperature changes of fiber Bragg gratings (FBGs) to the thermal expansion coefficients, Young’s moduli of optical fibers, and thicknesses of coating polymers. Using this model the Bragg wavelength shifts were calculated and compared with the measured wavelength shifts of FBGs with various coating thick...

The surface plasmon spectra of Langmuir-Blodgett (LB) films have been investigated by combining photoacoustic technique with resonant attenuated total reflection spectroscopy. By this technique, the experimental PA angular spectra of cadmium stearate LB films have been obtained. According to the electromagnetic theory and considering the anisotropic properties of LB films, as well as based on t...

We design, optimize, fabricate, and characterize highly reflective quasi-omnidirectional multilayered structures with a wide angular spectral range. consider chirped layers of gradually varying thicknesses made by stacking Bragg-type sub-structures, we maximized their numerically calculated reflectance averaged over different ranges keeping minimum thickness for given pairs refractive indices. ...

Femtosecond laser pulses are used to excite coherent optical phonons in single crystal Bi2Te3 thin films. Oscillations from lowand high-frequency A1g phonon modes are observed. A perturbation model based on molecular dynamics reveals various possibilities of phonon generation due to complex interactions among different phonon modes. In order to elucidate the process of phonon generation, measur...

The Agricultural Policy Environmental eXtender (APEX) model is capable of estimating edge-of-field water, nutrient, and sediment transport and is used to assess the environmental impacts of management practices. The current practice is to fully calibrate the model for each site simulation, a task that requires resources and data not always available. The objective of this study was to compare m...

We have fabricated titanium dioxide based dye-sensitized solar cells that incorporate corrosion-protected silver nanoparticles as plasmonic optical elements of the photoelectrode. The thickness of the TiO(2) layer separating the dye from the nanoparticles has been systematically varied using atomic layer deposition. Over the range of TiO(2) coating thicknesses examined (2 to 8 nm) there is clea...

Film thickness measurement can be realized using white light interferometry, but it is challenging to guarantee high precision in a large range of thicknesses. Based on scanning we propose spectral-temporal demodulation scheme for large-range measurement. The process remains unchanged either coatings or substrate-free films, while some adjustments are made according the estimated optical thickn...

The accuracy of quantitative stereological analysis tools such as the (physical) disector method substantially depends on the precise determination of the thickness of the analyzed histological sections. One conventional method for measurement of histological section thickness is to re-embed the section of interest vertically to its original section plane. The section thickness is then measured...
