ABSTRACT:
A power monitoring system including a first substrate having a first vertical cavity surface emitting laser and a second vertical cavity surface emitting laser formed thereon and being generally identical. A second substrate having a photodiode formed thereon. The second substrate is flip chip mounted on the first substrate with the photodiode in optical alignment the second vertical cavity surface emitting laser. The output of the photodiode is used to control emissions of the first and second vertical cavity surface emitting lasers.
