Abstract
A fiber optic assembly including an alignment plate having an M×N array of alignment holes formed thereon and an equal number of optical fibers, each bonded to a respective one of the alignment holes. A bondline, preferably an inorganic adhesive having a glass transition temperature of at least about 150° C., is located between each optical fiber and its respective alignment hole. The bondline is preferably less than about 200 nm in thickness. The inorganic adhesive is preferably formed from a colloidal suspension of sodium silicate.
Claims15
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.
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.
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.
