ABSTRACT:
An improved connector is provided. The connector comprises: an optoelectronic transducer having a transducer axis through a center of the optoelectronic transducer, and a first alignment means integrated with the optoelectronic transducer; an optical fiber having a fiber axis being different than the transducer axis; a first lens comprising a ball lens disposed between the optoelectronic transducer and the optical fiber, a center of the first lens aligned to the optoelectronic transducer axis by the first alignment means; and a second lens between the optical fiber and the first lens, a center of the second lens aligned to the fiber axis by a second alignment means; wherein the first and second lenses form an optical relay which relays light between the center of the optoelectronic transducer and the center of the optical fiber, forming an efficient optical coupling between the optoelectronic transducer and the optical fiber, even though the transducer axis and the fiber axis do not coincide. In addition, a method for manufacturing the connector is also disclosed.
