Therefractive index,n,of a material is the ratio of the velocity of light infree spaceto that in the material in question. Therefractive indexof glass is around 1.5. This means that light travels in glass at around 300000/1.5 = 200000km/s. It is a little publicised fact that the spee...
M.J. Withford, in Laser Growth and Processing of Photonic Devices, 2012 Refractive index measurements Variants of Fig. 10.5 (modified for the wavelength and type of glass of interest) can be used to estimate the peak refractive index change between the bulk material and the waveguide structures...
Factors affecting the refractive index dispersion are discussed by using the single-oscillator Drude-Voigt equation. The values of n d at 0.5876 μm are affected mainly by the average resonance wavelength at the ultraviolet region through all of the glass systems. The distinguishing features of ...

exactly cancelled by the μeff reduction such that neff [=(ɛeff× μeff)1/2] remains near unity in the long-wavelength regime (that is, when the wavelength is much larger than the array period and the fundamental resonance wavelength), regardless of the volume fraction of the particle16...
(1) is believed to provide a suitable model for the RI intact RBCs because the membrane is very thin compared to the wavelength of visible light14and has a low volume fraction16. In addition to the intrinsic complexity of measuring the optical properties of single microscopic cells compared to...
The density and refractive index of B2O3 glass quenched from 1200掳C at 40 kbar increase by 22.5% and 3.7%, respectively, relative to 1-atm values. On the basis of Raman spectroscopic evidence, it is proposed that the increase in the fraction of BO3 triangles in a closely packed random ...
