Claim 19:
20. An implantable device comprising:
one or more drivers, plural light emitting sources, and an optical element;
each of the one or more drivers configured to convert a digital data signal into one or more modulation signals to drive one or more of the light emitting sources;
each light emitting source configured to generate a light beam in response to a corresponding one of the one or more modulation signals, each light beam contributing to form a single optical signal; and
the optical element configured to direct the light beams to exit the implantable device distributed in a pattern in which a peak position of light intensity of each light beam is separated from a corresponding peak position of light intensity of an adjacent light beam by at least a first distance and less than a second distance, wherein the device is configured to be embedded within biological tissue and the first distance and the second distance are based on characteristics of the biological tissue.
