Anderson Localization Light Guiding in a Two-Phase Glass

Anderson localization has been realized in several different systems over the years. In this paper we describe a rather unique manifestation of phenomenon occurring two-phase glass composition that guides light. The glasses are borate or alkali borosilicate when heated separates into two distinct phases compositions, high index phase and low phase. When is with specific thermal schedule to develop separation it then drawn rod fiber, particulate forms elongated strands resulting random cross-sectional refractive pattern. This pattern maintained along length producing light guiding behavior significant distance propose an phenomenon.
