    摘要: An opto-isolator (10) increases optical efficiency by using holographic elements (22,24,26) to direct a beam of light (34) through an optical waveguide (20). An opto-electronic transmitter (12) and receiver (16) are connected to the waveguide to be in alignment with the beam of light reflected by the holographic elements. The transmitter and receiver are disposed on separate leadframe portions (14,18), and the opto-isolator is surrounded by a package (32).

    摘要: A optoelectronic module comprises one or more VCSELs electrically connected to an IC and optically connected to a fiber optic faceplate. The fiber optic faceplate, comprising a closely packed bundle of optical fibers, permits efficient capture of light from the VCSELs. Precise alignment of the faceplate with respect to the VCSELs is not needed since light not collected by one fiber is captured by another nearby optical fiber. One method of fabricating the module comprises forming substrate layers on both sides of the VCSELs such that features can be formed on the first substrate layer while the second temporary substrate layer provides structural support. The method further comprises forming apertures on the first substrate layer by etching. An etch stop buffer layer positioned between the first substrate layer and the VCSELs protects the VCSELs from being etched in the process. The second temporary substrate layer is removed after the fiber optic faceplate is mounted on the first substrate side. An alternate method of VCSEL fabrication comprises forming an aperture by patterning a dielectric layer above an active layer within the VCSEL. The aperture in the dielectric layer can be formed with a high degree of precisely using conventional patterning techniques. The dielectric layer is part of a current confinement element that concentrates current in an active region. A top DBR can also be formed of multiple layers of dielectric.

    摘要: A holographic optical interconnect system (100) and method (200) provide flexible, efficient interconnection of a plurality of circuit boards CBs and a plurality of integrated circuit chips. Each CB has at least an optically transparent substrate OTS mate parallel to the CB and extending outside a CB holder. Each OTS mate has parallel sides and carries at least two holographic optical elements HOEs. A first one of the HOEs on a first OTS mate reflects at least a predetermined portion of a first light beam transmitted by a transmitter on a corresponding CB to another HOE, which transmits a received light beam via free space outside the CB holder. On another OTS mate, two HOEs are utilized to receive and direct at least part of the light beam received to a detector on a corresponding CB via free space within the circuit board holder or reflection within the OTS mate.

    摘要: An optical interconnect system includes a stacked arrangement of optical lightpipe layers, one layer assigned to each emitter of the system. The various optical lightpipe layers are designed to provide the same level of light to each receptor of the system. The optical lightpipe layers are very thin, allowing the emitter and receptor devices of the system to span the entire optical lightpipe layer assembly. The path loss between every emitter and every receptor over the entire system can be balanced, i.e., made substantially the same, or otherwise set as desired with respect to individual emitters and receptors.
