ABSTRACT:
A coupling arrangement for coupling an optical fiber to a planar integrated optical component characterized by a V-shaped groove being formed in a surface of the substrate, at least one end of the groove being closed by a vertical substrate wall containing an optical window formed by an end of an integrated optical component in said substrate, and an end of an optical fiber being secured in said groove with an end face being positioned adjacent said optical window. The arrangement is preferably made by etching oblique channels into a substrate containing the optical component to form a bridge extending parallel with the optical component, the bridge is then removed to expose an optical window in a substantially vertically extending wall, and then the optical fiber is positioned and secured in the groove with the end face of the fiber being positioned adjacent the optical window.
