Abstract
Abstract An integrated optical component is described with ion diffused optical circuit paths in glass connected to optical fibers, comprising a transverse exit groove (6,10) machined adjacent the paths, a plateau (5,11) for supporting an uncoated portion of the optical fibers for connection to the paths, and a shoulder (4,12) 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. The method disclosed for manufacturing such a component comprises machining, approximate alignment, precise alignment, and gluing steps.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
149 words
An integrated optical component comprising a glass substrate with at least one optical circuit path connected to at least one optical fiber, said glass substrate including at least one transverse exit groove (6, 10) forming a vertical lateral surface (7) at a termination of said optical circuit path, an endface of said optical fiber abutting said termination at said vertical lateral surface, plateau support means (5,11) adjacent the side of said transverse exit groove opposite said optical circuit path, for supporting an uncoated portion of said optical fiber; and first adhesive means for securing said optical fiber endface to said vertical lateral surface characterized in that: said at least one optical circuit path is an ion diffused path, and said transverse exit groove is sufficiently wide to permit the end of the fiber that spans across the groove to be moved and precisely aligned with said circuit path termination.
Claim 2
Dependent Claim
23 words
The integrated optical component of claim 1, characterized in that the width of said transverse exit groove is between 2 and 6 mm.
Claim 3
Independent Claim
220 words
A method of manufacturing an integrated optical component which connects an optical fiber to an ion exchange optical circuit path including the steps of: forming a glass body substantially in the form of a rectangular glass block, creating at least one optical circuit path in said glass body, mechanically machining a vertical lateral surface to create a termination for said optical circuit path, forming a 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, characterized in that: said optical circuit path is formed in said glass body by ion exchange, and a transverse exit groove is machined instead of a transverse support shoulder so that the material left for forming the edge of said groove opposite the optical circuit path constitutes said plateau support means, said transverse exit groove is sufficiently wide to permit the end of the fiber that spans across the groove to be moved and precisely aligned with said circuit path termination, and the depth of said transverse exit groove is much greater than the diameter of said optical fiber.
Claim 4
Dependent Claim
21 words
The method of claim 3 characterized in that the width of said transverse exit groove is between 2 and 6 mm.
