Integrated circuits with optical interconnect

摘要

Optical interconnect that connects an integrated circuit to other circuitry is provided. An integrated circuit may be a composite integrated circuit having a Group IV portion and a compound semiconductor portion overlying an accommodating buffer. An optical component formed in the compound semiconductor portion may be configured to optically connect circuitry in the Group IV portion to external circuits. The optical component may be an optical source component or an optical detector component. A plurality of optical components may be formed in an integrated circuit to provide parallel optical interconnect. Two composite integrated circuits may be stacked with their active sides facing and with aligned optical components to allow for the circuits to communicate. Waveguides that are in a circuit board may also be used in connecting circuits that are supported by the circuit board.
