Zusammenfassung:Embodiments disclosed herein generally relate to a magnetic write head including a media facing surface and a surface opposite the media facing surface. The magnetic write head further includes a reflector extending from the surface opposite the media facing surface toward the media facing surface. A semiconductor laser diode gain region protrudes out of the surface opposite the media facing surface, and the reflector helps optimizing the optical energy generated in the semiconductor laser diode gain region to be a single mode over a large current and temperature range.
