Patent ID: 7258495

Claim:
An optical or optoelectronic package comprising a supporting structure, the supporting structure having at least one hole formed therein, the at least one hole having a sidewall; an optical or optoelectronic subsystem disposed upon the supporting structure, the optical or optoelectronic subsystem having an optical input or output; at least one lensed fiber stub assembly, the at least one lensed fiber stub assembly including a section of lensed fiber having a lensed end having a lens face, and a distal end having an endface, a lens alignment ferrule affixed to and holding the lensed end of the lensed fiber, the lens alignment ferrule being affixed to the optical or optoelectronic system or the supporting structure and holding the lens face of the lensed end of the lensed fiber in operative alignment with the optical input or output of the optical or optoelectronic system, and a package attachment ferrule having a distal endface and an exterior surface, the package attachment ferrule affixedly holding the distal end of the lensed fiber, the package attachment ferrule being attached to the sidewall of the at least one hole formed in the supporting structure, and disposed through the at least one hole, so that the endface of the distal end of the lensed fiber is optically coupled to the exterior of the supporting structure, wherein the package attachment ferrule has a proximal section and a distal section and the exterior surface of the proximal section is different from the exterior surface of the distal section.
