    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.

    Abstract: An improved optical printing head is described including a linear array of light sources, and a lens array comprised of graded index optical fibers arranged in a hexagonal close-packed array, there being at least three rows of individual fiber lenses. The linear array of light sources is aligned with, and parallel to, lines of symmetry of the graded index lens array, where the lines of symmetry are defined as lines along said graded index lens array which will transmit a line of light incident thereon with a minimum deviation in the intensity of light transmitted through the lens array. A photosensitive surface on a rotating drum is provided onto which light images from the optical printhead are incident. The print head can be used in optical printing machines.
