Abstract
An apparatus (10, 310) is provided including a first chip having at least one recess (18, 418) formed on the first chip, in the form of an optoelectronic/photonic device (12, 314), at a pre-selected location. A second chip, in the form of an optical component supporting substrate (14, 312), includes at least one projection (24, 424) extending therefrom at a pre-selected location, wherein at least one of the recess and the projection includes angled walls (28, 428) having an angle relative to the top of the wall less than 54.74° for capturing and directing the other of the at least one recess (18, 418) and the at least one projection (24, 424) for aligning the first chip to the second chip.
