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 tubular device comprising multiple streams that are merged, folded, bent or wrapped and forming radial stems and branches, wherein said tubular device is a coated optical photonic crystal fiber. 2. A tubular device according to claim 1 , wherein said stems are tapered radially inwards. 3. A tubular device according to claim 1 , wherein said stems are tapered radially outwards. 4. A tubular device according to claim 1 , wherein the stems have constant thicknesses. 5. A tubular device according to claim 1 , wherein the stems have different thicknesses. 6. A tubular device comprising multiple streams that are merged, folded, bent or wrapped and forming radial stems and branches, wherein said tubular device is a coated fiber that bends light. 7. A tubular device comprising multiple streams that are merged, folded, bent or wrapped and forming radial stems and branches, wherein said tubular device is a coated fiber that transmits light through a tube. 8. A tubular device according to claim 6 , wherein said stems are tapered radially inwards. 9. A tubular device according to claim 6 , wherein said stems are tapered radially outwards. 10. A tubular device according to claim 6 , wherein the stems have constant thicknesses. 11. A tubular device according to claim 6 , wherein the stems have different thicknesses. 12. A tubular device according to claim 7 , wherein said stems are tapered radially inwards. 13. A tubular device according to claim 7 , wherein said stems are tapered radially outwards. 14. A tubular device according to claim 7 , wherein the stems have constant thicknesses. 15. A tubular device according to claim 7 , wherein the stems have different thicknesses.
