Abstract
Abstract An optoelectronic connector (10) coupled to a fiber ferrule (38) containing an optical fiber (39) and a method for coupling the optoelectronic connector (10) to the fiber ferrule (38). The optoelectronic connector (10) has a base (11) and walls (13, 14, 17, and 18) that form a cavity (19). A semiconductor receiving area (26) extends into a first portion of the base (11) and an interconnect recess (27) extends into a second portion of the base (11). Alignment pins (31) extend from the second portion of the base (11). The optoelectronic connector (10) may be a unitary structure. The fiber ferrule (38) is inserted into the cavity (19) to form an optoelectronic device (30).
