摘要： 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.

摘要： The invention is a system and method for performing all-optical modulation. A semiconductor layer having a defined thickness has an insulator adjacent one surface of the semiconductor. Conductive layers are provided adjacent the semiconductor layer and the insulator. A photodetector is provided to generate an electric field across the conductive layers in response to an input optical gate signal. An input optical signal is modulated by interaction with a plasmon wave generated at the semiconductor/conductive layer interface. By defining the thickness of the semiconductor layer, a desired wavelength of light supports the plasmon waves. Operation of the all-optical modulator requires the provision of an input optical signal of a desired wavelength and the provision of a gate optical signal. An output optical signal is recovered and can be used to store, display or transmit information, for example over a fiber optic communication system, such as a telecommunication system.
