Abstract
An optical modulation system includes a metamaterial structure configured to receive and process an input optical signal at at least one operational wavelength, where the metamaterial structure changes between a transmissive state and a non-transmissive state with respect to the optical signal(s) at the operational wavelength(s) in response to an external stimulus applied to the metamaterial structure. An external stimulus source is coupled with the metamaterial structure and is configured to change the metamaterial structure between its transmissive and non-transmissive states by applying selected stimulus pulses to the metamaterial structure. The optical modulation system processes the input optical signal to output a modulated optical signal that modulates in correspondence with the selected pulses applied to the metamaterial structure.
