  • Publication number: 20020159673
    Abstract: An interconnect comprising an anisotropic conductive film and an optically transmissive unit embedded in the anisotropic conductive film. The optically transmissive unit provides an optically transmissive path through the anisotropic conductive film. In an alternative embodiment, an electronic package comprises a first substrate, a second substrate, and an interconnect located between the first substrate and the second substrate. The interconnect comprises an anisotropic conductive film for electrically coupling a first conductive element formed on the first substrate to a second conductive element formed on the second substrate and one or more optically transmissive units embedded in the anisotropic conductive film. At least one of the one or more optically transmissive units couples an optical signal path on the first substrate to an optical receiver on the second substrate.

  • Publication number: 20020154354
    Abstract: A multiprocessor system may include a plurality of processors that are optically coupled to one another. An optical transceiver may send messages to other processors using a preassigned wavelength. Each message from one of the other processors in the system may be received by a given processor. The messages from any given processor may include a code that identifies the sending and receiving processors. When a given processor is receiving a signal from another processor, it may provide an indication to the other processors in the system that it is occupied and will not accept any transmissions.

  • Publication number: 20020090178
    Abstract: A fiber optic connector system may include a elliptical reflector arranged to couple light from one optical fiber to another. The elliptical reflector has two foci, one of which may correspond to an end of a first optical fiber and the other of which may correspond to an end of another optical fiber. Thus, light emitted from one fiber may be coupled to another fiber.
