Method of splicing pairs of arrayed or individual fibers utilizing optical fiber aligning grooves

Claim 1

A method for joining a first optical fiber to a second such fiber comprising the steps of: placing said first and second fibers in respective first and second planes which converge toward each other and intersect a fiber receiving groove in two different places and at a slight angle thereto; advancing said first and second fibers toward each other along said planes and into said fiber receiving groove, said fibers entering said groove at a slight angle of inclination to said groove sufficient to generate within each fiber a downwardly biasing stress to maintain each said fiber in contact with said groove; continuing said advancing step until the ends of said first and said second fibers meet in abutting axial alignment; and joining said abutted fibers.

Claim 2

A method for joining a first optical fiber to a second such fiber comprising the steps of: placing said first and second fibers in respective first and second planes which converge toward each other and intersect a fiber receiving groove in two different places and at a slight angle thereto; advancing said first and second fibers toward each other along said planes and into said fiber receiving groove, said fibers entering said groove at a slight angle of inclination to said groove sufficient to generate within each fiber a downwardly biasing stress to maintain each said fiber in contact with said groove; continuing said advancing step until the ends of said first and said second fibers meet in abutting axial alignment; and joining said abutted fibers.

Claim 3

A method for joining a first linear array of optical fibers to respective ones of a second array comprising the steps of: placing said arrays in respective first and second planes which converge toward each other and interest a substrate surface, comprising a plurality of fiber receiving grooves having the same center-to-center spacing as said fibers, in two different places and at a slight angle thereto; advancing the fibers of said first and second linear arrays toward each other along said respective planes and into respective fiber receiving grooves, said fibers entering said grooves at a slight angle with respect to said grooves sufficient to generate within each fiber a downwardly biasing stress to maintain each fiber in contact with said respective groove; continuing said advancing step until the ends of corresponding fibers of said first and second arrays meet in abutting axial alignment; and joining said abutted fibers.

Claim 4

A method for joining a first linear array of optical fibers to respective ones of a second array comprising the steps of: placing said arrays in respective first and second planes which converge toward each other and interest a substrate surface, comprising a plurality of fiber receiving grooves having the same center-to-center spacing as said fibers, in two different places and at a slight angle thereto; advancing the fibers of said first and second linear arrays toward each other along said respective planes and into respective fiber receiving grooves, said fibers entering said grooves at a slight angle with respect to said grooves sufficient to generate within each fiber a downwardly biasing stress to maintain each fiber in contact with said respective groove; continuing said advancing step until the ends of corresponding fibers of said first and second arrays meet in abutting axial alignment; and joining said abutted fibers.

Claim 6

A method for joining a first linear array of optical fibers to respective ones of a second array comprising the steps of: forming parallel fiber receiving grooves on a substrate surface, said fiber receiving grooves having the same center-to-center spacing as said arrayed fibers; placing said arrays in respective first and second planes which converge toward each other and intersect with said substrate surface in two different places and at a slight angle thereto; advancing the fibers of said first and second linear arrays toward each other along said respective planes and into respective fiber receiving grooves, said fibers entering said grooves at said slight angle of inclination to said grooved surface sufficient to generate within each fiber a downwardly biasing stress to maintain each fiber in contact with said respective groove; continuing said advancing step until the ends of corresponding fibers of said first and second arrays meet in abutting alignment; and joining said abutted fibers.

Claim 7

A method for joining a first linear array of optical fibers to respective ones of a second array comprising the steps of: forming parallel fiber receiving grooves on a substrate surface, said fiber receiving grooves having the same center-to-center spacing as said arrayed fibers; placing said arrays in respective first and second planes which converge toward each other and intersect with said substrate surface in two different places and at a slight angle thereto; advancing the fibers of said first and second linear arrays toward each other along said respective planes and into respective fiber receiving grooves, said fibers entering said grooves at said slight angle of inclination to said grooved surface sufficient to generate within each fiber a downwardly biasing stress to maintain each fiber in contact with said respective groove; continuing said advancing step until the ends of corresponding fibers of said first and second arrays meet in abutting alignment; and joining said abutted fibers.
