摘要
Techniques are disclosed for aligning an optical transmitter with an optical receiver for a line-of-sight communications link, wherein the optical transmitter comprises a laser array emitter, the laser array emitter comprising a plurality of laser emitting regions, wherein each of a plurality of the laser emitting regions is configured to emit laser light in a different direction such that the laser array emitter is capable of emitting laser light in a plurality of different directions. The system can run produce emissions from different laser emitting regions until a laser emitting region that is in alignment with the optical receiver is found. This aligned laser emitting region can then be selected for use to optically communicate data from the optical transmitter to the optical receiver.

In a third embodiment, oxidation rather than ion implantation is used to create the grid of top-emitting lasing regions within the single structure. For example, a patterned etch can isolate conductive paths in a single structure, creating a grid of light sources. This structure exhibits multiple laser emission points from the single structure. The lasing structure is isolated with an etched region from the ground contact that forms the outside perimeter of the chip. This structure for Embodiment 3 is top emitting. The conductive areas of the grid are where light will be emitted. The positive electrical contact can be a grid with openings where the light is emitted.
