Abstract
Abstract An integrated optical component with ion diffused optical circuit paths in glass connected to optical fibers, comprising a transverse exit groove machined adjacent the paths, a plateau for supporting an uncoated portion of the optical fibers for connection to the paths, and a shoulder adjacent the plateau for supporting a coated portion of the fiber, the fiber endfaces being secured to the terminations of the paths by means of an adhesive; and, a method for manufacturing such a component comprising machining, approximate alignment, precise alignment, and gluing steps.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
138 words
A method for manufacturing an integrated optical component which connects an optical fiber to an ion exchange optical circuit path comprising: forming a glass body substantially in the form of a rectangular glass block; creating at least one optical circuit path in said glass body by ion exchange; mechanically machining at least one transverse exit groove to create an termination for said optical circuit path; mechanically machining a transverse support shoulder for supporting a coated or sheathed portion of said fiber; forming plateau support means for supporting an uncoated portion of said fiber; approximately aligning an endface of said fiber with said optical circuit path termination; precisely aligning said fiber endface and said optical circuit path termination by means of a micromanipulator tool; and, securing said fiber endface to said optical circuit path termination with an adhesive means.
Claim 2
Independent Claim
138 words
A method for manufacturing an integrated optical component which connects an optical fiber to an ion exchange optical circuit path comprising: forming a glass body substantially in the form of a rectangular glass block; creating at least one optical circuit path in said glass body by ion exchange; mechanically machining at least one transverse exit groove to create an termination for said optical circuit path; mechanically machining a transverse support shoulder for supporting a coated or sheathed portion of said fiber; forming plateau support means for supporting an uncoated portion of said fiber; approximately aligning an endface of said fiber with said optical circuit path termination; precisely aligning said fiber endface and said optical circuit path termination by means of a micromanipulator tool; and, securing said fiber endface to said optical circuit path termination with an adhesive means.
Claim 3
Dependent Claim
37 words
The method of claim 1 further comprising the step of mechanically machining a high surface quality for said termination of said optical circuit path, thereby forming an interface shoulder with a vertical lateral surface at said termination.
Claim 4
Dependent Claim
30 words
The method of claim 1 further comprising the step of securing said optical fiber to said support shoulder and said plateau support means by application of a single glue joint.
Claim 5
Dependent Claim
33 words
The method of claim 1 further comprising the step of precision grinding sectioned cavities in said plateau support means for use in approximately aligning said fiber endface and said optical circuit path termination.
Claim 6
Dependent Claim
14 words
The method of claim 1 wherein said adhesive means is a radiation curable glue.
