Abstract

A continuous, single-step, low-temperature process combines metal coating with the splicing of fibers, producing a single, continuous low-cost process for embedding fibers in metal, and/or the splicing of fibers with a joint featuring uniform composition and high strength requiring no additional adhesives. The method can be used to create terminations for cables, or it can be used as a method of splicing or joining optical fibers by positioning the ends of the two fibers under the foils, so that they abut prior to creating the bond. The consolidation material may be provided in sheets, with or without fiber-locating grooves or, alternatively, droplets may be used. In the preferred embodiment, ultrasonic vibrations are used as the source of consolidation energy. A range of metals are suited to the process, including aluminum, copper, titanium, nickel, iron and their alloys as well a numerous other metals of more limited structural utility.

Claims

1. A method of embedding one or more optical fibers into a matrix, comprising the steps of:

positioning an optical fiber onto a substrate;

supplying one or more increments of material so as to cover at least a portion of the fiber; and

bonding the increments using a process sufficient to consolidate the increments without melting the material in bulk.

2. The method of claim 1, wherein the material is electrically conductive.

3. The method of claim 2, further including the step of using the fiber for data transmission.

4. A product with embedded optical fibers made according to the method of claim 3.

5. The method of claim 2, further including the step of using the fiber for reinforcement.

6. The method of claim 2, further including the step of using the fiber as a sensor.

7. The method of claim 1, wherein the step of bonding the increments includes ultrasonically bonding the material.

8. A product with embedded optical fibers made according to the method of claim 7.

9. The method of claim 1, wherein two fibers which are disposed end-to-end within the material, thereby forming an interconnection.

10. The method of claim 1, wherein the material is a metal or alloy.

11. The method of claim 1, wherein the material is supplied in the form of layers.

12. The method of claim 1, wherein the material is supplied in the form of droplets.

13. The method of claim 1, further including the step of forming a groove in the substrate to receive the fiber.

14. The method of claim 1, wherein the substrate and the material are of the same composition.

15. A product with embedded optical fibers made according to the method of claim 1.

16. The method of claim 1, including a fiber which ends within the material, thereby forming a termination.

30. The method of claim 1, including the step of placing multiple fibers parallel to one another.

17. A method of embedding one or more optical fibers into a matrix, comprising the steps of:

providing a substrate of the material and positioning the optical fiber thereon;

supplying one or more increments of material so as to cover at least a portion of the fiber; and

ultrasonically bonding the increments to consolidate the increments without melting the material in bulk.

18. The method of claim 17, wherein the material is electrically conductive.

19. The method of claim 18, further including the step of using the fiber for data transmission.
