  • Nonreciprocal optical transmission device and optical apparatus including the same
    Patent number: 11262606
    Abstract: Nonreciprocal optical transmission devices and optical apparatuses including the nonreciprocal optical transmission devices are provided. A nonreciprocal optical transmission device includes an optical input portion, an optical output portion, and an intermediate connecting portion interposed between the optical input portion and the optical output portion, and comprising optical waveguides. A complex refractive index of any one or any combination of the optical waveguides changes between the optical input portion and the optical output portion, and a transmission direction of light through the nonreciprocal optical transmission device is controlled by a change in the complex refractive index.
    Type: Grant
    Filed: April 24, 2020
    Date of Patent: March 1, 2022
    Assignees: SAMSUNG ELECTRONICS CO., LTD., IUCF-HYU (INDUSTRY-UNIVERSITY COOPERATION FOUNDATION HANYANG UNIVERSITY)
    Inventors: Kiyeon Yang, Youngsun Choi, Seokho Song, Jaewoong Yoon, Choloong Han, Yongsung Kim, Jeongyub Lee, Changseung Lee
