Patents by Inventor Myeong Seok Oh

Myeong Seok Oh has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Light emitting diode and method of fabricating thereof
    Patent number: 6794211
    Abstract: The light emitting diode includes an intermediate layer made of non-single crystalline material between single crystalline layers. By the intermediate layer, the boundary characteristic between the single crystalline layers may be improved and the defect caused by the lattice mismatch can be decreased, so that the brightness and forward voltage characteristics can be improved.
    Type: Grant
    Filed: March 20, 2002
    Date of Patent: September 21, 2004
    Assignee: Samsung Electro-Mechanics Co., Ltd.
    Inventors: Myeong Seok Oh, Sung Wook Lim, Jeong Hwan Ahn
  • Two-wavelength laser diode, and manufacturing method therefor
    Publication number: 20030002549
    Abstract: A laser diode is disclosed, in which a laser diode for emitting the beams of a long wavelength and another laser diode for emitting the beams of a short wavelength are sequentially stacked upon a submount, thereby minimizing the gap errors and the position errors for the light emitting points. That is, the distance between the light emitting points can be minimized, and therefore, unlike in the conventional techniques, a separate additional optical component is not required. Accordingly the adjustment of the optical axis is rendered easier, and therefore, the yield is increased, while the assembling cost can be curtailed.
