Abstract
An optical control element having a substratehaving an electro-optic effect, an optical waveguideformed on the substrate, and a control electrodethat is provided on the substrate and controls the phase of light that propagates through the optical waveguide, in which the control electrodehas a plurality of resonant-type electrodesandthat are disposed along the optical waveguideand have different resonance frequencies (fand f), an feeder electrodethrough which control signals are input and branched signal electrodes that are branched from the feeder electrode are connected to the respective resonant-type electrodes, and the branched signal electrode is configured to match a timing at which the electric control signal is applied to each of the resonant-type electrodes and a timing at which the light that propagates through the optical waveguide passes at the section of each of the resonant-type electrodes.
