Stamping to form a composite structure of dissimilar materials having structured features

A composite structure includes a base and an auxiliary portion of dissimilar materials. The auxiliary portion is shaped by stamping. As the auxiliary portion is stamped, it interlocks with the base, and at the same time forming a desired structured feature on the auxiliary portion, such as a structured reflective surface, an alignment feature, etc. With this approach, relatively less critical structured features can be shaped on the bulk of the base with less effort to maintain a relatively larger tolerance, while the relatively more critical structured features on the auxiliary portion are more precisely shaped with further considerations to define dimensions, geometries and/or finishes at relatively smaller tolerances. The auxiliary portion may include a composite structure of two dissimilar materials associated with different properties for stamping different structured features.

METHOD AND APPARATUS FOR ALIGNING ARRAYS OF OPTICAL FIBERS

A method for manufacturing an array of optical fiber ferrules includes producing on a first side of a wafer a pattern of an array of disks or holes (111, 112) in a metallic coating (121, 122). The metallic coating is covered with a negative photoresist layer. A second side of the wafer opposite to the first side is illuminated with light that propagates as a divergent or collimated beam through the photoresist layer, thereby creating a conical pattern within the photoresist layer. The photoresist layer is developed to create conical apertures. A sheet with a conical openings pattern registered to the conical apertures is attached so that a small diameter of each conical opening of the sheet is smaller than, and in contact with, a large diameter of the conical aperture to which it is registered, thereby forming an array of optical fiber ferrules.
