Abstract: A light modulation device includes a dielectric antenna and a refractive-index-variable layer which faces the dielectric antenna and comprises a material having a refractive index that changes according to a signal. A light may be modulated, since resonance characteristics of the dielectric antenna are controlled according to a refractive-index change of the refractive-index-variable layer.
