    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.

    Abstract: GRATING COUPLED WAVEGUIDE LASER APPARATUS An optical coupling arrangement is described. A semiconductor laser is provided having two opposite end faces perpendicular to the axis of the emission stimulated therein. A first reflective surface adjacent to and parallel with one of the end faces reflects back into the laser radiant energy tending to exit through the one laser end face. An optical wave guide is coupled to receive the radiant energy exiting from the face opposite the first reflective surface. A grating integral with the optical waveguide directs radiant energy out of the waveguide in the direction not parallel to the lasing axis. A mirror reflects radiant energy back through the waveguide and the laser to support the lasing action.

    Abstract: An optical assembly structure wherein miniature optical components such as lasers, modulators, lenses, thin-film and fiber-optic waveguides, and photodetectors are critically aligned and supported for coactive operation by means of two or more wafers which are formed with complementary grooves and mortises to support the loose optical components such as lenses and fiber-optic waveguides and to receive alignment rails to insure the relativity of the wafers, which also have formed integral therewith optical elements such as waveguides, modulators, and lasers, to produce an integrated optical assembly somewhat in the manner of an "optical bench," wherein the bench structure also provides an active optical element.
