Abstract

A preform for making a vortex optical fiber comprises a glass cylinder formed substantially of silicone dioxide that defines a core portion along a longitudinal axis of the glass cylinder and a cladding portion surrounding the core portion. The glass cylinder further defines a plurality of holes running parallel to the longitudinal axis from a first end of the glass cylinder to a second end of the glass cylinder.

Claims (30)

1. A vortex optical fiber prepared by a process comprising the steps of:

generating a preform comprising a glass cylinder formed substantially of silicone dioxide that defines a core portion along a longitudinal axis of the glass cylinder and a cladding portion surrounding the core portion, wherein the glass cylinder further defines a plurality of holes running parallel to the longitudinal axis from a first end of the glass cylinder to a second end of the glass cylinder;

heating the preform to generate a thread from the second end of the glass cylinder;

drawing the thread at a predetermined speed using drawing components to generate the vortex optical fiber with a predetermined diameter;

winding the vortex optical fiber onto a spool; and

wherein the process generates the vortex optical fiber having the core portion along a second longitudinal axis of the vortex optical fiber and the cladding portion surrounding the core portion.

2. The vortex optical fiber of claim 1 , wherein the step of generating further comprises the step of forming the core portion along the longitudinal axis within the glass cylinder.

3. The vortex optical fiber of claim 1 , wherein the step of generating further comprises the step of creating the plurality of holes within the preform.

4. The vortex optical fiber of claim 3 , wherein the step of creating further comprises drilling the plurality of holes within the preform.

5. The vortex optical fiber of claim 1 , wherein the step of generating further comprises generating the preform to include a first hole along the longitudinal axis of the glass cylinder through the core portion and a plurality of second holes located between the first hole and a circumference of the glass cylinder through the cladding portion.

6. The vortex optical fiber of claim 1 , wherein the preform defines a refractive index profile that contains a valley along the longitudinal axis of the glass cylinder and a pair of peaks along edges of the core portion within the cladding portion.

7. The vortex optical fiber of claim 6 , wherein the vortex optical fiber defines a second refractive index profile that contains a valley along the longitudinal axis of the glass cylinder and a pair of peaks along edges of the core portion within the cladding portion.

8. A method for generating a vortex optical fiber comprising:

generating a preform comprising a glass cylinder formed substantially of silicone dioxide that defines a core portion along a longitudinal axis of the glass cylinder and a cladding portion surrounding the core portion, wherein the glass cylinder further defines a plurality of holes running parallel to the longitudinal axis from a first end of the glass cylinder to a second end of the glass cylinder;

heating the preform to generate a thread from the second end of the glass cylinder;

drawing the thread at a predetermined speed using drawing components to generate the vortex optical fiber with a predetermined diameter;

winding the vortex optical fiber onto a spool; and

wherein the process generates the vortex optical fiber having the core portion along a second longitudinal axis of the vortex optical fiber and the cladding portion surrounding the core portion.

9. The method of claim 8 , wherein the step of generating further comprises forming the core portion along the longitudinal axis within the glass cylinder.

10. The method of claim 8 , wherein the step of generating further comprises creating the plurality of holes within the preform.

11. The method of claim 10 , wherein the step of creating further comprises drilling the plurality of holes within the preform.

12. The method of claim 8 , wherein the step of generating further comprises generating the preform to include a first hole along the longitudinal axis of the glass cylinder through the core portion and a plurality of second holes located between the first hole and a circumference of the glass cylinder through the cladding portion.

13. The method of claim 8 , wherein the preform defines a refractive index profile that contains a valley along the longitudinal axis of the glass cylinder and a pair of peaks along edges of the core portion within the cladding portion.

14. The method of claim 13 , wherein the vortex optical fiber defines a second refractive index profile that contains a valley along the longitudinal axis of the glass cylinder and a pair of peaks along edges of the core portion within the cladding portion.

15. The method claim 8 further comprising the step of coating the fiber with a protecting coating.

16. The method of claim 8 , wherein the step of drawing further comprises the steps of:

determining a current diameter of the vortex optical fiber drawn from the preform;

comparing the current diameter of the vortex optical fiber to the predetermined diameter;

increasing a draw speed if the current diameter of the vortex optical fiber exceeds the predetermined diameter; and

decreasing a draw speed of the current diameter of the vortex optical fiber falls below the predetermined diameter.
