摘要： When phases of lights passing through arms are adjusted, a first DC bias and a first modulation signal are applied to one arm from one modulating electrode, and a second DC bias and a second modulation signal are applied to the other arm from the other modulating electrode. The first and second DC biases are applied to the modulating electrodes such that a rate of a product of a length of one modulating electrode and the first DC bias and a product of a length of the other modulating electrode and the second DC bias is kept at a constant value. According to this constitution, it is possible to enable an optimum control of a phase difference between the arms and a precise control of wavelength chirp characteristics with a simple element constitution, and an optical modulation of which device size is small and having fine characteristics is enabled.
