Abstract:
1. A method for aligning optical components included in an optical component assembly and optical waveguides included in an optical waveguide assembly according to a common optical axis and by using an adapter, the method comprising: providing the optical component assembly with a substrate having the optical components disposed at a mid-portion of the substrate, and a 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; providing 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; providing the optical waveguide assembly with a second alignment structure comprising a distinct step structure designed according to the position of the waveguides within the waveguides assembly; and positioning the optical component assembly, the optical waveguide assembly and the adapter, so that a sidewall of the cavity and the distinct step structure are put in contact with a sidewall of the first step structure.
