    • An optical transmitter generating an arbitrary optical waveform including an analog optical waveform, which is capable of controlling a bias to a Null point easily. The optical transmitter modulates light from a light source by an optical modulator with use of a data sequence being an electric signal, to thereby generate the arbitrary optical waveform, and includes: a light intensity detector detecting intensity of output light of the optical modulator; a data signal generator generating the data sequence; an average modulation degree calculator calculating an average modulation degree of the data sequence based on the data sequence; and a bias controller performing bias control on the optical modulator based on the intensity of the output light detected by the light intensity detector and the average modulation degree of the data sequence calculated by the average modulation degree calculator.
