ABSTRACT:
Various aspects of the present invention are directed to photonic devices configured to control transmission of electromagnetic radiation through a resonator structure. In one aspect of the present invention, a photonic device includes at least one electromagnetic resonator and a state-change material operably coupled to the at least one electromagnetic resonator. The state-change material is capable of being reversibly transitioned between a high-resistivity state and a low-resistivity state, with a ratio of the resistivity of the high-resistivity state to the resistivity of the low-resistivity state being at least about 100. Transmission of electromagnetic radiation through the at least one electromagnetic resonator at an operational frequency is controllable by transitioning the state-change material between the high-resistivity state and the low-resistivity state. Methods for controlling transmission of a signal are also disclosed.
