Abstract

See full text

An optical modulator includes an electro-optic layer including an electro-optic material, and a material layer arranged below the electro-optic layer and having a dielectric constant lower than a dielectric constant of the electro-optic layer. The optical modulator includes a core layer arranged below the material layer and having a refractive index higher than refractive indices of the electro-optic layer and the material layer, and an electrode that applies an electric signal to the electro-optic layer. The refractive index of the material layer is 0.85 times the refractive index of the electro-optic layer or higher.
