Physical Aging and Refractive Index of Optical Polymer Glass

Refractive Index Determinations of Glass Fragments

Analysis of the use of tapered graded-index polymer optical fibers for refractive-index Sensors.

The behavior of tapered graded-index polymer optical fibers is analyzed computationally for different refractive indices of the surrounding medium. This serves to clarify the main parameters affecting their possible performance as refractive-index sensors and extends an existing study of similar structures in glass fibers. The ray-tracing method is employed, its specific implementation is expla...

Optimum refractive-index profile of the graded-index polymer optical fiber, toward gigabit data links.

The optimum refractive-index distribution of the high-bandwidth graded-index polymer optical fiber (POP) was clarified for the first time by consideration of both modal and material dispersions. The ultimate bandwidth achieved by the POP is investigated by a quantitative estimation of the material dispersion as well as the modal dispersion. The results indicate that even if the refractive-index...

Characterization of Chromatic Dispersion and Refractive Index of Polymer Optical Fibers

The chromatic dispersion and the refractive index of poly(methyl methacrylate) polymer optical fibers (POFs) have been characterized in this work by using a tunable femtosecond laser and a Streak Camera. The characterization technique is based on the measurement of the time delays of light pulses propagating along POFs at different wavelengths. Polymer fibers of three different lengths made by ...

Study on Optical Constants and Refractive Index Dispersion of Neutral red Doped Polymer Film

Problem statement: The some optical constants polymer thin film with red dye 3-amino-7dimethylamino-2-methyl phenazine (NR) as the guest material and Polyvinylpyrrolidone (PVP) as the host material were prepared by adulteration and spin-coating methods. Approach: The values of some important parameters (refractive index n, extinction coefficient K and dielectric constant ε∞) of polymer thin fil...
