ABSTRACT:
An optical modulation device includes a split ring resonator having a slit. An optical waveguide exhibiting an electro-optical effect has a portion located near the slit of the resonator. A light beam can travel in the optical waveguide. A voltage can be induced in the resonator in response to a modulating signal. The induced voltage causes an electric field at the slit of the resonator. The electric field depends on the modulating signal. The electro-optical effect enables the light beam to be changed in response to the electric field. Thus, the light beam is modulated in accordance with the modulating signal. The resonator may be replaced by a split ring electrode.
