Abstract
An apparatus for self-aligning an optical fiber to an optical waveguide. The apparatus includes an optical waveguide chip including: one or more optical waveguides formed on a first substrate, each optical waveguide having a protruding portion; and one or more alignment rails formed on the first substrate, each alignment rail spaced apart from each optical waveguide by a predetermined distance; and an alignment jig including: one or more grooves formed in a second substrate, each groove adapted to receive one protruding portion and each groove supporting one optical fiber in alignment with one optical waveguide; and one or more alignment grooves formed on the second substrate, each alignment groove spaced apart from the grooves by the predetermined distance and adapted to mate with the alignment rails.
