Methods of epsilon-near-zero optical modulation
Abstract
A method of optical modulation in a non-resonant epsilon-near-zero (EMZ) plasmonic electro-optical modulator is provided. An optical carrier is injected into a waveguide optically coupled to a layer of transparent conductive material having an epsilon-near-zero (ENZ) wavelength. The transparent conductive material layer constitutes a portion of a capacitive structure that includes a gate dielectric layer. A time-varying bias voltage applied across the gate dielectric layer shifts the ENZ wavelength toward the carrier wavelength, and thereby impresses a phase modulation pattern on the carrier wave.
