Abstract

See full text

An optical modulator includes: a substrate made of a material having an electro-optical effect; an optical waveguide formed on the substrate; and a modulation electrode for modulating an optical wave propagating through the optical waveguide, wherein emitted light emitted from the optical waveguide is guided by optical fiber, and polarization of the substrate is reversed in a predetermined pattern along the optical waveguide so as to provide waveform distortion having a characteristic opposite to a wavelength dispersion characteristic of the optical fiber.
