Abstract

Aspects and techniques of the present disclosure relate to a fiber alignment device that includes curved-type alignment bores. Another aspect of the present disclosure relates to methods of forming the fiber alignment device with curved-type alignment bores.

First claim

What is claimed is:

1. A fiber alignment device comprising:
a one piece alignment body having a first end and an opposite second end;
an alignment bore extending between the first and second ends of the one piece alignment body, wherein the one piece alignment body defines and fully encircles the alignment bore; and
an intermediate region positioned between the first and second ends of the one piece alignment body;
the alignment bore having first and second curved portions located on opposite sides of the intermediate region;
wherein the alignment bore has a diameter of no more than 1.5 microns larger than a maximum outer diameter of an optical fiber.

2. The fiber alignment device of claim 1 , wherein the first and second curved portions are symmetrical.

3. The fiber alignment device of claim 1 , wherein the intermediate region includes a fiber contact location.

4. The fiber alignment device of claim 3 , wherein the first and second curved portions of the alignment bore define first and second curved passages that extend along a fiber insertion axis between the first and second ends of the one piece alignment body to receive first and second optical fibers.

5. The fiber alignment device of claim 4 , wherein upon insertion of the first and second optical fibers into the first and second curved passages, the first and second curved portions cause the first and second optical fibers to be biased toward one side of the alignment bore.

6. The fiber alignment device of claim 5 , wherein ends of the first and second optical fibers meet at the fiber contact location of the intermediate region.

7. The fiber alignment device of claim 1 , wherein the alignment bore has a diameter of no more than 1.0 microns larger than a maximum outer diameter of an optical fiber.

8. The fiber alignment device of claim 1 , wherein the alignment bore has a diameter of no more than 0.5 microns larger than a maximum outer diameter of an optical fiber.

9. The fiber alignment device of claim 1 , wherein the alignment bore has a diameter of 125.5 to 126.5 microns.

10. A multi-fiber alignment device comprising:
a one piece alignment body having a first end and an opposite second end;
a plurality of alignment bores extending between the first and second ends of the one piece alignment body, wherein the one piece alignment body defines and fully encircles each one of the plurality of alignment bores; and
an intermediate region positioned between the first and second ends of the one piece alignment body;
each one of the plurality of alignment bores having first and second curved portions located on opposite sides of the intermediate region;
wherein each one of the plurality of alignment bores has a diameter of no more than 1.5 microns larger than a maximum outer diameter of an optical fiber.

11. The multi-fiber alignment device of claim 10 , wherein each one of the first and second curved portions of the plurality of alignment bores are symmetrical.

12. The multi-fiber alignment device of claim 10 , wherein the intermediate region includes a fiber contact location.

13. The multi-fiber alignment device of claim 12 , wherein each one of the first and second curved portions of the plurality of alignment bores define first and second curved passages that extend along a fiber insertion axis between the first and second ends of the one piece alignment body to receive first and second optical fibers.

14. The multi-fiber alignment device of claim 13 , wherein upon insertion of each of the first and second optical fibers into each of the first and second curved passages, the first and second curved portions cause the first and second optical fibers to be biased toward one side of the respective alignment bore.

15. The multi-fiber alignment device of claim 14 , wherein ends of the first and second optical fibers meet at the fiber contact location of the intermediate region.

16. The multi-fiber alignment device of claim 10 , wherein each one of the plurality of alignment bores has a diameter of no more than 1.0 microns larger than a maximum outer diameter of an optical fiber.

17. The multi-fiber alignment device of claim 10 , wherein each one of the plurality of alignment bores has a diameter of no more than 0.5 microns larger than a maximum outer diameter of an optical fiber.

18. The multi-fiber alignment device of claim 10 , wherein each one of the plurality of alignment bores has a diameter of 125.5 to 126.5 microns.

19. A fiber alignment device comprising:
a one piece alignment body having a first end and an opposite second end;
an alignment bore extending between the first and second ends of the one piece alignment body, wherein the one piece alignment body defines and fully encircles the alignment bore;
an intermediate region positioned between the first and second ends of the one piece alignment body; and
a cutout feature defined in a bottom surface of the one piece alignment body, the cutout feature defining the alignment bore with a varying wall thickness, the varying wall thickness being configured for providing differential cooling during processing;
the alignment bore having first and second curved portions located on opposite sides of the intermediate region.
