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.
