  • Patent number: 9830937
    Abstract: 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.

  • Patent number: 9576595
    Abstract: A mounting surface of a read/write head is prepared to receive an epitaxial layer. The mounting surface is proximate a waveguide of the read/write head, and the waveguide is configured to receive an optical output from the epitaxial layer. The epitaxial layer is transfer printed on to the mounting surface. The mounting surface maintains a vertical alignment between the optical output and the waveguide. The epitaxial layer is processed to form a laser integrated with the read/write head.
