摘要
An optical modulator includes an optical waveguide, a modulating electrode, a conductive layer, an electric signal input section, and connector members. At least a portion of the optical waveguide is made of an electro-optic material. The modulating electrode includes a first conductor line and a second conductor line, which are coupled together electromagnetically, and applies a modulating electric field to a portion of the optical waveguide. The conductive layer forms a first microstrip line with the first conductor line and a second microstrip line with the second conductor line, respectively. Through the electric signal input section, an RF modulating signal is supplied to the modulating electrode. The connector members connect the first and second conductor lines together at both ends. In this optical modulator, the first and second conductor lines function as an odd-mode resonator for the RF modulating signal.
