Abstract

See full text

An optical modulator having a small-sized circuit and a smaller voltage drop in a terminating resistor is provided. The optical modulator includes first and second optical waveguides, a first electrode inputting a first high frequency signal into the first optical waveguide, a second electrode inputting a second high frequency signal having a reverse phase relative to the first high frequency signal into the second optical waveguide, a first terminating resistor connected to the first electrode, a second terminating resistor connected to the second electrode, a connection point connecting the first and second electrodes via the first and second terminating resistors, and a DC voltage supply connected to the connection point. A resistance value of the first terminating resistor is equal to a characteristic impedance of the first electrode. A resistance value of the second terminating resistor is equal to a characteristic impedance of the second electrode.
