Patent number: 9830937Abstract: A laser is configured to emit light along a substrate-parallel plane along a first surface of the laser. An etched facet is on an emitting end of a lasing cavity and an etched mirror is on another end of the lasing cavity. An etched shaping mirror redirects light received from the etched facet in a direction normal to the substrate-parallel plane. A slider comprises an optical input coupler configured to couple the light from the laser into a waveguide of the slider. At least one protrusion is disposed on the laser and at least one recession is disposed on the slider, the at least one protrusion and the at least one recession configured to align the laser with the slider to allow the light to be coupled into the optical input coupler.Type: GrantFiled: January 18, 2017Date of Patent: November 28, 2017Assignee: SEAGATE TECHNOLOGY LLCInventors: Roger L. Hipwell, Jr., Jon Paul Hurley, Scott Eugene Olson, Ralph Kevin Smith, Joseph Michael Stephan
