  • Patent number: 10555692
    Abstract: Disclosed herein are a method and a device for sensing sugars, using terahertz electromagnetic waves. By the method, even a trace amount of sugars in a liquid state can be accurately discriminated and sensed, with high sensitivity and selectivity, using a sensing chip that works in a terahertz electromagnetic wave band. Using the method, sugars even at low concentrations can be accurately analyzed with high sensitivity and selectivity in which terahertz electromagnetic waves are irradiated onto sugars through a sensing chip having a meta unit in which a pattern is formed to amplify a frequency corresponding to an absorption frequency of a sugar of interest.

  • Patent number: 9261714
    Abstract: A plasmonic all-optical switch includes a graphene layer, a first dielectric layer located on the graphene layer, a nano-antenna located on the first dielectric layer, and a second dielectric layer located on the nano-antenna. An incident beam is propagated by means of a surface plasmon wave generated at an interface between the graphene layer and the first dielectric layer. Further, localized surface plasmon resonance is selectively generated at an interface between the nano-antenna and the second dielectric layer by means of a pump beam incident to the nano-antenna to decrease an intensity of the incident beam. The plasmonic all-optical switch may operate at an ultrahigh speed just with a small light energy without any electric method, greatly reduce power consumption of an IT device by applying to an all-optical transistor or the like, and increase a processing rate.
