Abstract
A vision-based passive alignment approach to optically couple input/output of optical fibers in optical alignment to optoelectronic components that are supported on a substrate. An optical bench supporting an optical fiber is physically and optically coupled to an optoelectronic device mounted on a submount via an optically transparent alignment block. The transparent alignment block having a first set of optical fiducials for aligning optical fiducials defined on the optical bench with the alignment block, and a second set of optical fiducials for aligning the alignment block with optical fiducials defined on the submount.
