摘要： An optical subassembly for transferring light between an optoelectronic converter and an optical fiber where the housing and the lens are of plastic in which the housing is made to dimensions within the precision of molded plastic and the lens imparts focusing properties that compensate for the limitations of the plastic technology. Alignment in the X-Y plane only is employed. The lens has a first surface focused on the optoelectronic converter which substantially collimates the light through the lens and a second surface that introduces deliberate longitudinal spherical aberration that compensates for component position. Attachment or fixing of the optoelectronic converter to the housing is accomplished by RF heating a TO can to quickly cure an epoxylayer.
