Abstract: 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.

Abstract: Optical alignment of optical subassembly and optoelectronic device is achieved using an external source and an external receiver, passing optical signal through a passive waveguide in the optoelectronic device, via alignment reflective surface features provided on the optical subassembly. The optical subassembly is provided with a first alignment reflective surface directing alignment signal from the source to a grating coupler at the input of the waveguide, and a second alignment reflective surface directing to the receiver the alignment signal directed from a grating coupler at the output of the waveguide after the alignment signal has been transmitted from the input to the output through the waveguide. By adjusting the relative position between the optical subassembly and the optoelectronic device, and detecting the maximum optical power of the alignment signal reflected from the second alignment reflective surface, the position of best optical alignment of the optical subassembly and the optoelectronic device can be determined.

Abstract: An expanded beam ferrule includes a first ferrule halve having first reflective surfaces and a second ferrule halve having second reflective surfaces, which together retain optical fibers. The pair of reflective surfaces output collimated light parallel to the mid-plane of the ferrule. An external sleeve aligns the external surface of two similar ferrules, with corresponding second reflective surfaces of the ferrules facing each other. Output light from an optical fiber held in one ferrule is bent twice by the pair of reflective surfaces, with beam divergence after the first bent, and collimation after the second bent. The collimated light is transmitted to the facing second reflective surface in a facing second ferrule aligned by the sleeve, which is subject to optical reshaping in reverse to that undertaken in the first ferrule, so as to converge and focus light to input to the optical fiber held in the other ferrule.

Abstract: An expanded beam ferrule includes a first ferrule halve having reflective surfaces and a second ferrule halve, which together retain optical fibers. The reflective surfaces output light perpendicular to the mid-plane of the ferrule. A sleeve aligns the external surface of two similar ferrules, with the reflective surfaces of the respective ferrules facing each other. Output light from an optical fiber held in the first ferrule is bent and collimated by a reflective surface, transmitted to the facing reflective surface in a second ferrule aligned by the sleeve, which bends the light to input to the optical fiber held in the second ferrule. The ferrule components and/or sleeve are precision formed by high throughput metal stamping. The ferrule is incorporated in an optical fiber connector.
