Optoelectronic module and method of manufacturing the same

摘要

A light-emitting element is mounted on a first conversion element mounting portion prepared on a lead frame and resin-molded by using a mold. In this case, a focusing lens whose optical axis coincides with the major surface of the light-emitting element and a coupling portion in which a sleeve is fitted are integrally molded at once to mold a transmission section and an electronic circuit section. When these member are fixed in housings, and a ferrule holding an optical fiber is inserted in the sleeve fitted in a recess portion of the coupling portion, the optical fiber is optically coupled to the major surface of the light-emitting element. At this time, when the distal end portion of the sleeve is brought into contact with the abutment portion in the coupling portion, the end face of the optical fiber always coincides with the major surface of the light-emitting element, thereby realizing reliable optical axis alignment. <IMAGE>
