Abstract
Official abstract text for this publication.
The disclosed embodiments generally relate to extruding multiple layers of micro- to nano-polymer layers in a tubular shape. In particular, the aspects of the disclosed embodiments are directed to a method for producing a Bragg reflector comprising co-extrusion of micro- to nano-polymer layers in a tubular shape.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for producing a Bragg reflector comprising co-extrusion of micro- to nano-polymer annular stream of layers produced by layer multiplication in the direction of extrusion in a single continuous process to form a seamless tubular shape, wherein the annular layers are of constant thickness and contain at least two materials of differing refractive indices. 2. A method according to claim 1 , wherein said tubular shape contains a core. 3. A method according to claim 2 , wherein said core is hollow. 4. A method according to claim 1 , wherein said layer thickness is ¼ the wavelength of the desired output wavelength. 5. A method according to claim 1 , wherein said tubular-shaped Bragg reflector comprises an outer cladding.
