Die Stack with Optical TSVs

摘要

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.

1. An apparatus comprising:
a first die comprising:
a laser source for generating a source unmodulated optical beam, andone or more first optical beam routing structures for optically transmitting the source unmodulated optical beam through the first die; and at least one receiving die comprising:
one or more second optical beam routing structures for optically receiving at least a portion of the source unmodulated optical beam from the one or more first optical beam routing structures,a modulator for generating an output modulated optical beam which is encoded at said modulator in response to electrical signal information, andone or more third optical beam routing structures for optically transmitting the output modulated optical beam signal through the receiving die.
