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, approximately alignment, precise alignment, and gluing steps.
