First principles calculations of electronic and optical properties of multiferroic oxide BiFeO3 are used in combination with a plasmonic device model of optical switch to show that a BiFeO3 based device can have much better performance than devices based on existing materials. A prototype of a plasmonic resonator with an R-BFO thin film layer is used as an example and shows excellent switch and modulation responses.
