  • Nanoscale plasmonic field-effect modulator
    Patent number: 9864109
    Abstract: A plasmonic device having a transparent conducting oxide (TCO) waveguide and a tunable voltage applied across the TCO and a metal layer for modulating an input optical signal.
    Type: Grant
    Filed: October 21, 2016
    Date of Patent: January 9, 2018

  • Optical modulating device having gate structure
    Patent number: 9632216
    Abstract: An optical modulation device includes a plasmonic nano-antenna layer, a metal layer that faces the plasmonic nano-antenna layer, and a permittivity variation layer and a dielectric material layer between the plasmonic nano-antenna layer and the metal layer. An active area formed in the permittivity variation layer according to an external signal may function as a gate that controls optical modulation performance.
