1. A system for combining the output of semiconductor light devices to generate a single light beam, comprising:

  • a set of one or more semiconductor light devices configured to generate a plurality of light beams representing a first channel of data;

    a binary string containing digital data, each bit from the binary string controlling a power of each of the one or more semiconductor light devices from the set of one or more semiconductor light devices, wherein an amplitude of a light beam generated by each semiconductor light device is determined by a position of a particular bit controlling each semiconductor light device, the amplitude encoding the digital data in the light beam;

    a lens array positioned over the set of semiconductor light devices and configured to focus the plurality of light beams to a single focal point; and

    a macro lens positioned beyond the lens array and configured to collimate the plurality of light beams into the single light beam carrying the digital data for the first channel.
