Abstract
Official abstract text for this publication.
One embodiment of the invention includes a method for forming an optical fiber. The method comprises providing a preform having a core material and a glass cladding material surrounding the core material. The method also comprises drawing the preform at a temperature that is greater than a melting temperature of the core material to form a drawn fiber. The method further comprises cooling the drawn fiber to form the optical fiber having a crystalline fiber core and a cladding that surrounds the crystalline fiber core and extends axially along a length of the crystalline fiber core.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of forming an optical fiber, the method comprising: providing a preform having a semiconductor core material and a glass cladding material surrounding the semiconductor core material; drawing the preform at a temperature that is greater than a melting temperature of the semiconductor core material to form a drawn fiber; and cooling the drawn fiber from a molten state to spontaneously crystallize the semiconductor core material to form the optica…
