  • 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: 8987052
    Abstract: Sub-micron precision alignment between two microelectronic components can be achieved by applying energy to incite an exothermic reaction in alternating thin film reactive layers between the two microelectronic components. Such a reaction rapidly distributes localized heat to melt a solder layer and form a joint without significant shifting of components.
