Abstract

A high density, low power, high performance information system, method and apparatus are described in which a laser source (213) on a first die (210) generates a source light beam of unmodulated monochromatic coherent light (281) for distribution via optical beam routing structures (e.g., 214/214a, 224/224a, 234/234a) to a plurality of receiving die (220, 230), each of which includes its own modulator (e.g., 223, 233) for optically receiving at least a portion of the source light beam (281a, 281b) from the first die and generating therefrom an output source light beam of modulated monochromatic coherent light (291, 292) which is encoded at said modulator in response to electrical signal information.
