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.

說明書

The oxidation length can be seen in FIG. 7 as dotted lines, all about the same distance from any one exposed edge or holes in the large single structure that has holes formed in it. FIG. 7 also shows the large single mesa ground structure. Three views of cross sections are illustrated to identify where FIGS. 7A, 7B, and 7C are located. Note 7B which clearly shows through this cross section that the mesa in the center is a single structure.

FIG. 7 shows:

    • 7001 Frame (Single Shorted Mesa) for Electrical Contact to Ground of Electrical Waveguide
    • 7002 Etched region isolating large single mesa from Ground Frame
    • 7003 Single Mesa Structure with Etched Holes
    • 7004 Indents in Edges to keep edges of Single Mesa Structure Oxidized and Non Conductive
    • 7005 Etched Hole in Single Mesa Structure
    • 7006 Oxidation Pattern around any Etched Edges
    • 7007 Overlapped Oxidized Areas not allowing Current Flow
    • 7008 Laser Aperture where Current Flows freely (same as 761 in FIG. 7B)
    • 7009 Gap in Shorted Mesa Structure to Reduce Capacitance from Ground to Signal Pad on Electrical Waveguide
