Abstract
Systems and methods are provided for modulating light of a wavelength of interest. The modulator assembly includes a plasmonic layer that supports surface plasmon polaritons at the wavelength of interest and a layer of solid-state phase change material having a first phase in which it is substantially transparent to light of the wavelength of interest and a second phase in which it is substantially opaque to light of the wavelength of interest. A control mechanism is configured to alter the phase of the solid-state phase change material between the first phase and the second phase. Each of the plasmonic layer and the layer of solid-state phase change material are configured as to provide a plasmonic mode of transmission for light of the wavelength of interest.
