An optical interconnect architecture provides three dimensional optical interconnects, with the optical interconnects provided along a plane such as a wafer or a substrate. One or more integrated circuits is provided on a second "electronic" plane that is spaced from the optical interconnect plane. Signals from the circuit on the electronic plane are coupled to the optical interconnect plane using various strategies, including metal or optical interlayer interconnects extending perpendicular to the optical plane. Once on the optical interconnect plane, the signals from the circuits on the electronic plane are propagated optically.
