Abstract
An optical coupling structure includes a common substrate carrying a pair of parallel ridges as a first engagement structure, a first sub-carrier mounted on the common substrate, the first sub-carrier carrying a second engagement structure including a plurality of groove pairs such that one of the groove pairs engage with the ridges forming the first engagement structure, and a second sub-carrier mounted on the common substrate. The second sub-carrier carrys a third engagement structure including a plurality of groove pairs such that one of the groove pairs engage with the ridges. The groove pairs are selected such that an optical component held by the first sub-carrier aligns optically to an optical component held by the second sub-carrier.
