Abstract
A photonic/plasmonic device is disclosed that uses a ferroelectric material and its magnetization state in order to affect the physical properties of electromagnetic waves. The magnetization state of the ferromagnetic material may either be zero or nonzero. When the magnetization state of the ferromagnetic material is non-zero physical properties of the electromagnetic waves are altered. This effect can be used to make switches and the like.
