Abstract:
1. An apparatus for aligning optical components with optical waveguides according to a common optical axis, comprising: an optical component assembly comprising a substrate having the optical components disposed at a mid-portion of the substrate, and a first alignment structure associated with the substrate of the optical component assembly, the first alignment structure comprising a cavity formed at opposing sides of the mid-portion of the substrate, such that a depth of the cavity corresponds to a line passing through center positions of the optical components; an adapter configured to have the optical component assembly positioned thereon, the adapter having a base surface comprising a first step structure disposed along a first axis and a second step structure disposed along a second axis perpendicular to the first axis, wherein a bottom surface of the cavity is in contact with the first and second step structures; and an optical waveguides assembly comprising the optical waveguides and a second alignment structure comprising a distinct step structure designed according to the position of the waveguides within the waveguides assembly; wherein the optical component assembly, the optical waveguide assembly and the adapter are positioned so that a sidewall of the cavity and the distinct step structure are in contact with a sidewall of the first step structure.
