The wavelength dispersion of the refractive index d n/dλ is constant up to 5 mol.% P 2O 5 producing a refractive index difference of 5×10 -3 compared with fused silica. Consequently, this glass materials is thought to be suitable for wide band-width optical fiber applications....
The refractive index and optical attenuation of sputtered SiO2–Ta2O5 waveguide film were measured in the 0.633–1.32-μm wavelength region. The waveguide film had a large refractive-index range of 1.46–2.08, which can be adjusted by suitable selection of the composition ratio of the SiO2–Ta2...

It is shown that the films, which can be produced with a refractive‐index range from 1.46 to 2.08 at 6328 Å wavelength by suitably selecting the ratio of the target constituents, exhibit a low optical transmission loss of less than 0.8 dB/cm for the TEmode.关键词:...
The refractive index of SiO2 is greater than that of the surrounding medium, so light is bent when it passes through a SiO2 particle. The amount of bending depends on the wavelength of the light and the size of the particle. The scattering of light by a SiO2 particle can be either ...

meters. The size of the optimally functioning nanoparticle is basically determined by the effective mode field range and effective refractive index. Furthermore, by FDTD, the optical field localization at the working wavelength is determined. Considering that the size of the nanoparticles is much ...
