Sleeved optical fiber for reduced lateral loss and method for making the same
View Patent ↗A fiber optic, and method for making the same, having glass cladding diameters, or overall glass diameters, or glass-clad sections upon polymer clad fiber, that are large than the bulk of the fiber.
1. A fiber optic comprising a short section of fluorine-doped tubing fused about a terminal end of a polymer clad, silica core fiber where a reflective bevel is polished on a terminal end of the fused section for the purpose of redirecting light laterally with respect to the fiber axis.
2. A fiber optic comprising a short section of fluorine-doped tubing fused about a terminal end of a fluorine-doped silica clad, silica core fiber, where a reflective bevel is polished on a terminal end of the fused section for the purpose of redirecting light laterally with respect to the fiber axis.
3. A fiber optic comprising a short section of pure silica tubing fused about a terminal end of a fluorine-doped silica clad, silica core fiber where a reflective bevel is polished on a terminal end of the fused section for the purpose of redirecting light laterally with respect to the fiber axis.
4. The fiber optic according to claim 1 where the dopant in the tubing is uniform throughout.
5. The fiber optic according to claim 2 where the dopant in the tubing is uniform throughout.
6. The fiber optic according to claim 1 where the dopant in the tubing varies in concentration within the radius of the tubing.
7. The fiber optic according to claim 2 where the dopant in the tubing varies in concentration within the radius of the tubing.
8. The fiber optic according to claim 1 where the dopant in the tubing varies in concentration along the axis of the tubing.
9. The fiber optic according to claim 2 where the dopant in the tubing varies in concentration along the axis of the tubing.
10. The fiber optic according to claim 2 where a reflective bevel is polished on a terminal end of the fused section for the purpose of redirecting light laterally with respect to the fiber axis.
11. The fiber optic according to claim 1 wherein the bevel tipped fiber is further disposed within a protective silica cap.
12. The fiber optic according to claim 10 wherein the bevel tipped fiber is further disposed within a protective silica cap.
13. The fiber optic according to claim 3 wherein the bevel tipped fiber is further disposed within a protective silica cap.
14. The fiber optic according to claim 11 where the fiber conducts light from a laser to the terminal end for the purpose of treating tissues in surgery.
15. The fiber optic according to claim 12 where the fiber conducts light from a laser to the terminal end for the purpose of treating tissues in surgery.
16. The fiber optic according to claim 13 where the fiber conducts light from a laser to the terminal end for the purpose of treating tissues in surgery.
