... Index of Refraction The amount of refraction depends upon the difference between the speeds of light in the two media. The index of refraction for a material is the ratio of the speed of light in a vacuum to the speed of the light in the material. • A low index of refraction (near 1) causes light t ...

Properties of Multilayer Optics
... Upon strong reflection off a layer a standing wave is formed which effectively changes the refractive index felt by the total field. If the Bragg peak is placed near Brewster’s angle, only the s-component feels this electric field modulation and change in refractive index which causes a phase shift ...
