英文摘要	An apparatus includes a slider body, a write element, and a laser chip. The write element is disposed on the slider body and is configured to apply a magnetic field to write data on a portion of a heat-assisted magnetic recording media in response to an energizing current. The laser chip has a laser diode with an active region configured to produce light. The laser diode adapted to inject the light to the proximate the read/write element. The laser chip additionally has a photodetector The photodetector is adapted to monitor light from the laser diode. The photodetector shares a same active region as the laser diode and the laser diode and photodetector are integrated together on the same laser chip.
