摘要： Herein disclosed is an optical modulator, comprising: an optical waveguide (3); and a traveling wave electrode (4) including an interaction portion (9) for modulating a phase of incident light and an input feed-through portion (7), in which the optical modulator further comprises at least one impedance transformation portion for reducing an impedance mismatching between a characteristic impedance of the interaction portion and at least one of characteristic impedances of the input feed-through portion, a connector electrically connected to the input feed-through portion, and an external circuit, at least one of the impedance transformation portions has a characteristic impedance which is different from a geometric mean of the characteristic impedances of said interaction portion and said input feed-through portion, a geometric mean of the characteristic impedances of the interaction portion and the connector, or a geometric mean of the characteristic impedances of the interaction portion and the external circuit.
