  • Leadframe and leadframe assembly for parallel optical computer link
    Patent number: 6137158
    Abstract: Parallel optical coupling apparatus for coupling a connector attached to one end of a parallel optical cable to a receiver or transmitter array. A parallel fiber optic assembly includes a receiver or transmitter array subassembly that houses a parallel optical coupler for transferring optical signals from an array of sources (e.g., lasers) in the assembly to the connector, or from the connector to an array of receiving elements in the assembly. A connector shell is provided that properly aligns the connector with respect to the optical coupler array.

  • Optical coupler
    Patent number: 6075913
    Abstract: An optical coupler. The coupler has an optical element for transferring an optical signal from an entrance region, external to the optical unit, to an exit region, also external to the optical unit. The coupling element has a first substantially planar transmitting surface lying in a first plane, a second substantially planar transmitting surface lying in a second plane not coplanar with the first plane, a first substantially planar reflecting surface substantially perpendicular to the first transmitting surface, and a second substantially planar reflecting surface substantially parallel to the first reflecting surface, and a shaped reflecting surface substantially perpendicular to and adjoining the first and second reflecting surfaces.
