Abstract

An apparatus for integrating optical devices between a module and a circuit board comprising a carrier having optical waveguides, a module having optical ports on a surface of the module, the surface of the module connected to the carrier such that the optical waveguides are in communication with the optical ports; and a circuit board having optical ports on a surface of the circuit board, the surface of the circuit board connected to the carrier such that the optical waveguides are in communication with the optical ports. The apparatus may also integrate electrical ports on the surface of the module, the surface of the circuit board, and electrical connections on the carrier. The apparatus may also integrate circuit chips having optical ports for communication with the optical waveguides.
