ABSTRACT:
An alignment method and construction for fiber optics communication modules. A module includes a plano-convex element, a concave element , and a fiber-holding substrate. The plano-convex element has first and second surfaces. The first surface is flat; the second surface has a convex segment characterized by a self-conjugate plane coincident with the first surface and a surrounding flat segment parallel to the first surface. The concave element has a concave surface segment surrounded by a flat segment. When the flat segment of the concave element is bonded to the flat segment of the plano-convex element, the first surface of the latter is also a self-conjugate plane for the concave segment. The substrate has a first flat face that is bonded to the first surface of the plano-convex element and a second flat face having a fiber-receiving means therein. Batch assembly and alignment may be achieved by fabricating carrier elements containing arrays of the plano-convex elements or concave elements.
