Abstract
In an example embodiment, an optical communication system includes an implantable optical transmitter and an external optical receiver. The transmitter includes a housing having one or more drivers, plural light emitting sources, and an optical element arranged therein. Each driver converts a digital data signal into modulation signals to drive the sources. Each source generates a light beam in response to a corresponding modulation signal, each light beam contributing to form a single optical signal. The optical element directs the light beams to exit the housing such that 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. The optical receiver includes at least one photodiode that detects light generated by the sources and generates a reconstructed data signal.
