ARRANGEMENT FOR PLACEMENT AND ALIGNMENT OF OPTO-ELECTRONIC COMPONENTS

摘要

An arrangement for providing passive alignment of optical components on a common substrate uses a set of reference cavities, where each optical device is positioned within a separate reference cavity. The reference cavities are formed to have a predetermined depth, with perimeters slightly larger than the footprint of their associated optical components. The reference cavity includes at least one right-angle corner that is used as a registration corner against which a right-angle corner of an associated optical component is positioned. The placement of each optical component in its own reference cavity allows for passive optical alignment to be achieved by placing each component against its predefined registration corner.

1. An optical assembly, comprising:
a common substrate including a planar surface comprising a plurality of openings defining a plurality of cavities in the common substrate, each of the cavities of the plurality of cavities formed by internal surfaces comprising a bottom surface and a plurality of wall surfaces that extend from the planar surface to the bottom surface, wherein two of the wall surfaces for each cavity form a right-angle registration corner; and a plurality of optical components received within the plurality of cavities and arranged in a spatial relationship wherein each of the plurality of optical components is arranged to exchange an optical signal with a respective other one of the plurality of optical components and supported by the common substrate, wherein each of the plurality of optical components includes a corner abutting against a respective one of the plurality of right-angle registration corners.
