Patent number: 7728399Abstract: Apparatuses and methods directed to an integrated circuit package having an optical component are disclosed. The package may include an integrated circuit die having at least one light sensitive region disposed on a first surface thereof. By way of example, the die may be a laser diode that emits light through the light sensitive region, or a photodetector that receives and detects light through the light sensitive region. An optical concentrator may be positioned adjacent the first surface of the first die. The optical concentrator includes a lens portion positioned adjacent the light sensitive region and adapted to focus light.Type: GrantFiled: July 22, 2008Date of Patent: June 1, 2010Assignees: National Semiconductor Corporation, The Regents of the University of CaliforniaInventors: Randall L. Walberg, Luu T. Nguyen, Robert Dahlgren, James B. Wieser, Kenneth Pedrotti, Jacob A. Wysocki
