摘要：
The present invention is an apparatus and method for providing detection of a laser output on a semiconductor wafer. A laser cavity and a detection cavity are formed on a semiconductor wafer in parallel such that light emitted laterally from the laser cavity is detected by the detection cavity. The amount of light detected can then be transformed into data, which in turn can be used to control the output of the laser.
