  • Reflected light wavelength scanning device including silicon photonics interrogator
    Patent number: 11781888
    Abstract: A reflected light wavelength scanning device having a silicon photonics interrogator is provided. The device includes: a light source module for outputting broadband light; an optical sensor that receives light output from the light source module through a circulator, reflects light in a specific band to the circulator, and transmits light in a band other than the specific band; and an interrogator for selectively injecting the polarized light by separating the polarized light from the reflected light input through the circulator.
    Type: Grant
    Filed: December 2, 2021
    Date of Patent: October 10, 2023
    Inventors: Hyung Myung Moon, Seung Chan Kwak, Jin Bong Kim, Sangyoon Han
