Abstract: A spherical depression lens is formed in a spherical depression in the substrate of the waveguide and a waveguide index lens is formed over the depression lens whereby the combination of the two lenses provides a high resolution waveguide lens for optical waveguides.

Abstract: MAGNETIC FIBER OPTIC CASTING APPARATUS A mold having a vee-shaped groove receives an optical fiber end in butted relationship with either another fiber end or with a mold wall surface which is perpendicular to the vee-shaped groove. Field forces are generated which urge unattached and disposable fiber seating elements into the groove, the seating elements in turn pushing the optical fiber end(s) into the groove until the side surface of the optical fiber end(s) arc in tangential contact with both sides of the vee-shaped groove. While the optical fiber end(s) are so positioned, casting liquid is introduced into the vee-shaped groove. The seating elements remain within the casting. YO979-041

Abstract: SELF-ALIGNED ~LUG CONNECTOR FOR OPTICAL FIBERS Abotract A casting is made of a corner having three mutually intersecting flat surfaces, one of:which :is perpendicular to the other two, while a fiber end Ls positioned against the corner in an orientation such that the end of the fiber butts against said one corner surface and the side surface:of the fiber tangentially touches said ot:her two corner surfaces. Two such castings, cach carrying a~;fibcr~end, ~rc aligned with each other i;n:an~alignment frame having two ~flat alignment surfaces which~are oriented wLth :respect t~ each other at the~same: orientation as the two corner surfaces~which tangentiallx:touch :the~fiber side~surface. Since these orientations are the same, the castings fit precisely intQ the groove formed by the two flat alignment surfaces of the frame and can be moved toward each other . until they touch. In this position the fiber ends carried by the castings are butt aligned.
