  • Patent number: 10168474
    Abstract: Disclosed are an optical input/output device and an opto-electronic system including the same. The device includes a bulk silicon substrate, at least one vertical-input light detection element monolithically integrated on a portion of the bulk silicon substrate, and at least one vertical-output light source element monolithically integrated on another portion of the bulk silicon substrate adjacent to the vertical-input light detection element. The vertical-output light source element includes a III-V compound semiconductor light source active layer combined with the bulk silicon substrate by a wafer bonding method.
    Type: Grant
    Filed: May 30, 2017
    Date of Patent: January 1, 2019
    Assignee: ELECTRONICS AND TELECOMMUNICATIONS RESEARCH INSTITUTE

  • Patent number: 9164238
    Abstract: Provided are an optical coupler and an arrayed-waveguide grating structure including the same. The coupler includes a lower clad layer, a core comprising a slab waveguide region disposed on one side of the lower clad layer and a ridge waveguide region disposed on the other side of the lower clad layer, and an upper clad disposed on the core, wherein the ridge waveguide region comprises a self-focusing region configured to focus an optical signal provided form the slab waveguide region and thus to prevent scattering of the optical signal.
