Abstract:
A method of manufacturing a package assembly for a surface-emitting optical transmitter, comprising the steps of:mounting a surface emitting optical transmitter to a leadframe;forming a package having a top surface, the package enclosing said optical transmitter and a first portion of said leadframe to provide a locating flange formed from said leadframe and disposed outside of said package;aligning the optical transmitter in a first direction relative to the locating flange to determine a height of the optical transmitter above the locating flange, wherein the first direction is substantially perpendicular to the leadframe; andmounting an optical element near the top surface of the package and above the optical transmitter in a manner that optically couples the optical element to the optical transmitter and aligns the optical element relative to the locating flange.
