ABSTRACT:
A semiconductor laser package including a mounting structure at least partially encapsulating a vertical cavity surface emitting laser and a photodetector. The vertical cavity surface emitting laser generating an emission along a path. The photodetector optically positioned and/or integrally formed with the vertical cavity surface emitting laser to receive a portion of the emission. An optical element is optionally positioned in the path, mounted on the mounting structure utilizing a snap-fit connection, a threaded or adhesive mounting. The mounting structure and optical element are fabricated to allow for proper z-axis alignment of the optical element relative to the laser emission aperture.
