  • Optical unit featuring both photoelectric conversion chip and semiconductor chip wrapped with flexible sheet
    Patent number: 7504701
    Abstract: In an optical unit including a photoelectric conversion chip adapted to be optically connected to an optical fiber, and a semiconductor chip for driving the photoelectric conversion chip, both the photoelectric conversion chip and the semiconductor chip are wrapped with a flexible sheet, to thereby produce an enveloper enveloping the photoelectric conversion chip and the semiconductor chip therein. At least a part of the enveloper is formed as a transparent area for allowing an optical connection between the optical fiber and the photoelectric conversion chip.
    Type: Grant
    Filed: February 20, 2007
    Date of Patent: March 17, 2009
    Assignees: NEC Electronics Corporation, NEC Corporation
    Inventors: Shigeru Moribayashi, Yoshiaki Morishita, Kowashi Taketomi, Takao Yamazaki, Shinji Watanabe, Ichiro Hatakeyama
