Claim Text:
1. A method comprising: forming an optical through silicon via in a silicon substrate of an integrated circuit, wherein the optical through silicon via comprises a nitride layer as an optical transmission medium, and wherein the optical through silicon via is formed by etching the nitride layer to recess a top surface of the nitride layer to below a top surface of the silicon substrate, and forming a silicon epilayer over a top surface of a remainder of the nitride layer; forming a photo detector within the integrated circuit optically coupled to a first side of the optical through silicon via; forming a set of electrical elements coupled to the photo detectors; and providing a light generating source optically coupled to a second side of the optical through silicon via; wherein the photo detector is configured to receive a light, generated by the light generating source, propagating through the optical through silicon via, and wherein the light, generated by the light generating source, is an optical signal controlled by a signal generated by the signal generating source; wherein the photo detector is further configured to convert the optical signal to an electrical signal, and wherein the electrical signal is distributed to the set of electrical elements.
