Photochromic glass containing tantalum oxide for optical fiber fabrication
TLDR
In this article, the authors proposed a core glass for photochromic optical fibers with refractive indices higher than about 1.52 and preferably higher than 1.58, which is suitable for optical fiber production.Abstract:
This invention relates to photochromic glass compositions containing about 10-50 percent by weight Ta2O5 which have refractive indices higher than about 1.52, and, preferably, higher than about 1.58, thereby rendering them especially suitable as a core glass in the production of photochromic optical fibers.read more

Drawing laminated polarizing glasses
TL;DR: In this paper, a method for making polarizing glasses having high dichroic ratios by drawing relatively small silver-containing particles under relatively high stress and elongating such particles during the drawing process without rupturing the glass draw by coating the polarizing glass with a substantially low viscosity skin glass is presented.

Cladding glasses for photochromic optical fibers
TL;DR: In this article, the discovery of glass compositions suitable for cladding photochromic optical fibers was discussed, which are particularly useful because, in addition to combining proper thermal expansion and refractive index with good ultraviolet light absorption, they do not deleteriously effect the natural fading rate of the photo chromic core glass during the fabrication of the cladded fiber optic.

Sizing composition and glass fibers sized therewith
TL;DR: In this article, a sizing composition for glass fibers is provided, comprising polyvinyl acetate, water dispersible epoxy resin and numerous lubricants, wherein the sized glass fibers are used in fiber optics for the transmission of light or images from one point to another, which sizing enables further processing of the glass fibers without substantial loss in transmission.
