Claims
- 1. A fiber optic assembly comprising:an alignment plate having at least one alignment hole formed thereon having a first diameter and a perimeter; at least one optical fiber having a second diameter, the first diameter being smaller than the second diameter, each of the at least one optical fiber being inserted into a respective one of the at least one alignment hole; and a bondline formed between each of the at least one optical fiber and the respective one of the at least one alignment hole, the bondline comprising an inorganic adhesive having a glass transition temperature of at least about 150° C.
- 2. The assembly of claim 1, wherein the inorganic adhesive is a sol-gel.
- 3. The assembly of claim 2, wherein the adhesive is sodium silicate.
- 4. The assembly of claim 3, wherein the sol-gel is about 14% NaOH and about 27% SiO2.
- 5. The assembly of claim 1, wherein the first diameter is about 1% larger than the second diameter.
- 6. The assembly of claim 1, wherein the alignment plate further comprises a face and the at least one optical fiber is oriental orthogonally with respect to the face of the alignment plate.
- 7. The assembly of claim 1, wherein the at least one optical fiber comprises at least three adjacent optical fibers and an interstitial cavity is located between the at least three adjacent optical fibers, the interstitial cavity being filled with an organic coating.
- 8. The assembly of claim 7, wherein the organic coating comprises an epoxy.
- 9. The assembly of claim 1, wherein the bondline is less than about 200 nm in thickness.
- 10. A fiber optic assembly comprising:an alignment plate having at least one alignment hole formed thereon having a first diameter and a perimeter; and at least one optical fiber having a second diameter, the first diameter being smaller than the second diameter, each of the at least one optical fiber being inserted into a respective one of the at least one alignment hole, each of the at least one optical fiber being bonded to a respective one of the at least one alignment hole along a bondline; wherein the bondline is less than about 200 nm in thickness and comprises a sol-gel having a glass transition temperature of at least about 150° C.
- 11. The assembly of claim 10, wherein the sol-gel is sodium silicate.
- 12. The assembly of claim 11, wherein the sol-gel is about 14% NaOH and about 27% SiO2.
- 13. A fiber optic assembly comprising:a plurality of optical fibers bonded to a plurality of holes formed in an alignment plate along a plurality of bondlines by an inorganic adhesive, the bondlines corresponding to lines of contact between each of the plurality of optical fibers and a respective one of the plurality of holes formed in the alignment plate, wherein the inorganic adhesive is formed from a colloidal suspension of sodium silicate.
- 14. The assembly of claim 13, wherein the colloidal suspension of sodium silicate comprises about 14% NaOH and about 27% SiO2.
- 15. The assembly of claim 14, wherein the bondline is less than about 200 nm in thickness.
