Abstract
A passively aligned high performance optoelectronic package in pigtail form which has a reduced cost over the conventional techniques of packaging by virtue of materials and alignment techniques is disclosed. The package of the present disclosure has a ferrule made of material which substantially matches the thermal characteristics of the optical bench, with the ferrule having a flat portion on one end for securing an optical fiber on a receiving group of the optical bench. The material of the ferrule is preferably kovar. Finally, passive alignment of the optoelectronic device to the fiber is effected by way of the ferrule with the flat portion of the ferrule being partially disposed in a second ferrule or sleeve prior to commitment of the sub-assembly into the final package.
