Abstract:
The features of optical control of the surface plasmon-polariton propagation in plasmonic circuits based on thin metal waveguides and semiconductor nanostructures are considered. The model of a plasmon resonator with additional elements based on semiconductor materials exhibiting strong photoconductivity is proposed. Using the numerical simulation, we show the possibility of switching the flow of surface plasmon-polaritons by switching on/off the external optical pump field changing the contribution of the light-induced conductivity of the control elements.
Keywords:
surface plasmon polaritons, metal plasmonic waveguide, photoconductivity, plasmonic resonator.
