摘要：An optical modulator comprises an electrode which applies to an opticalwaveguides of a Mach-Zehnder type optical interference system a first electric signal

based on an alternating current signal S and a direct current bias V, an electrode whichapplies to an optical waveguide of the Mach-Zehnder type optical interference system asecond electric signal based on an alternating current signal S and a direct current bias V,and a bias setting section which sets average direct current levels of the first and secondelectric signals based on signal frequency information D which indicates a magnituderelation between a maximum frequency of the alternating current signal S and amaximum frequency of the alternating current signal S
