Abstract
A semiconductor laser package including a laser chip mounted to a leadframe, and a plastic resin housing for encapsulating the laser chip. The laser chip composed of a vertical cavity surface emitting laser and a photodetector. The vertical cavity surface emitting laser generating an emission along a path. The leadframe being positioned a fixed distance from an emission window formed in the plastic resin housing. The laser chip mounted in precise z-axis alignment from the emission window utilizing the leadframe as a dimensional reference point, with the bump height compensating for variations in laser chip dimension. An optical element is optionally positioned in the path to reflect a portion of the emission.
