First Claim
Patent Images
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.

Abstract
Embodiments comprise laser emitter devices that generate a collimated beam of light the intensity or amplitude of which may be varied so as to carry data signals at a high rate of efficiency, and that is less sensitive to alignment of the detector, and detector systems for detecting the same collimated beam and reading the data carried in the beam of light.
