An article of manufacture comprising an optical-ready substrate made of a
first semiconductor layer, an insulating layer on top of the first
semiconductor layer, and a second semiconductor layer on top of the
insulating layer, wherein the second semiconductor layer has a top
surface and is laterally divided into two regions including a first
region and a second region, the top surface of the first region being of
a quality that is sufficient to permit microelectronic circuitry to be
formed therein and the second region including an optical signal
distribution circuit formed therein, the optical signal distribution
circuit made up of interconnected semiconductor photonic elements and
designed to provide signals to the microelectronic circuit to be
fabricated in the first region of the second semiconductor layer.
