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.

Abstract: A laser diode includes a substrate and a junction layer disposed on the substrate. The junction layer forms a quantum well of the laser diode. The laser diode includes a junction surface having at least one channel that extends through the junction layer to the substrate. The at least one channel defines an anode region and a cathode region. A cathode electrical junction is disposed on the junction surface at the cathode region, and an anode electrical junction is disposed on the junction surface and coupled to the junction layer at the anode region. A cathode metal layer is disposed in at least a trench region of the channel. The cathode metal layer couples the substrate to the cathode electrical junction.
