Si/SiO 2 /Au/uricase-uric acid/prism LRSPR sensor structure is utilized to detect uric acid (Concentration: 0.05 mM - 1 mM).. The developed LRSPR sensor illustrated high sensitivity. The refractive index determines how much the path of light is bent, or refracted, when entering a material.This is described by Snell's law of refraction, n 1 sinθ 1 = n 2 sinθ 2, where θ 1 and θ 2 are the angles of incidence and refraction, respectively, of a ray crossing the interface between two media with refractive indices n 1 and n 2.. Refractive Index Profiles of Optical Fiber. In simple words to understand, refractive index is the relative speed of light in a medium compared to the speed in vacuum. Thus if a medium have a refractive index of 1.5, the light will travel through that medium with a speed of 1/1.5 i.e. 0.67 times the speed of light in vacuum the relation between the reflectivity r and the refractive index n. Taking the refractive index range of optical glass from 1.4 to 2.1 the reflection factor P ranges from 0.92 to 0.75.

The refractive index (or index of refraction) of a medium is a measure for how much the speed of light (or other waves such as sound waves) is reduced inside the medium.For example, typical soda-lime glass has a refractive index of 1.5, which means that in glass, light travels at times the speed of light in a vacuum. Two common properties of glass and other transparent materials are directly. Refractive index - why is it important in PECVD? Refractive index is a good indicator of film composition, i.e. Si:N ratio or Si:O ratio. (If Si content is high, the refractive index will be high) It can be easily measured by ellipsometer or prism coupler, allowing rapid evaluation of film composition (and unifomrity of composition) Abstract: A lens formed of a high-refractivity low-dispersion glass and free of fogging and scorching on its optical-function surface, which is obtained by precision press-molding of an optical glass having a refractive index (nd) of over 1.83, an Abbe's number (?d) of 40 or more and a glass transition temperature (Tg) of 640° C. or lower and containing no Li2O and has one form of a meniscus. N2 - Silicon dioxide is common low-refractive index material used for example in optical interference coatings, in active devices as dielectrics or in microelectromechanical systems (MEMS) as sacrificial layers [1]. Depending on device and substrate limitations different process temperatures for film formation are encountered

Therefore, the effective index is changed, especially for longer wavelengths. This type of refractive index change versus wavelength due to different geometry is called waveguide dispersion . As these narrow waveguides (~1-3 μm core diameter) are combined with ultrashort pulses at the zero-dispersion wavelength pulses are not instantly destroyed by dispersion refractive index of amorphous alumina based on pure bin-ary aluminosilicate glass optical fibers.
