Semiconductor laser package with power monitoring system

摘要

A semiconductor laser package including a plastic resin housing for encapsulating a vertical cavity surface emitting laser. The semiconductor laser package including a mounting base, a surround can and a cap. The cap having integrally formed therein a power monitoring system, such as a photodetector. The vertical cavity surface emitting laser generating an emission along a path. The photodetector optically positioned to receive a portion of the emission. The power monitoring system including a plurality of layers of an amorphous silicon material and/or a germanium material.
