  • Light emission device including output coupler and optical apparatus adopting the same
    Patent number: 10950749
    Abstract: Provided are light emission devices including an output coupler and optical apparatuses having the same. The light emission device may include a QD layer containing quantum dots and a nano-antenna structure including an output coupler configured to control an output characteristic of light emitted from the QD layer. The output coupler may be configured to output an emission wavelength of the QD layer. The nano-antenna structure may include one of a metallic antenna, a dielectric antenna, and a slit-containing structure, or may have a multi-patch antenna structure or a fishbone antenna structure.
    Type: Grant
    Filed: October 30, 2018
    Date of Patent: March 16, 2021
    Assignees: SAMSUNG ELECTRONICS CO., LTD., CALIFORNIA INSTITUTE OF TECHNOLOGY
    Inventors: Duhyun Lee, Ruzan Sokhoyan, Yu-Jung Lu, Ghazaleh Kafaie Shirmanesh, Harry A. Atwater, Ragip A. Pala, Chan-Wook Baik
