  • Optical interconnect device and method for manufacturing the same
    Patent number: 8107776
    Abstract: An optical interconnect device includes a first substrate, a second substrate, an optical waveguide, an electrical wiring and a switching device. The first substrate has an electrical wiring circuit, an electrical-optical converter for converting an electrical signal to an optical signal, and a light emitting device for emitting a light. The second substrate has an electrical wiring circuit, an optical-electrical converter for converting the optical signal to the electrical signal, and a light receiving device for receiving the light from the light emitted device. The optical waveguide optically connects the light emitting and light receiving devices. The electrical wiring electrically connects the electrical wiring circuits of the first and second substrates. The switching device determines a fast signal of data to be transmitted via the optical substrate and a slow signal of data to be transmitted via the electrical wiring.
