摘要： An optical modulator includes a first coupler that branches an input light into two and outputs a first output light and a second output light; a first Mach-Zehnder interferometer (MZI) that modulates the intensity of the first output light from the first coupler and outputs a third output light; a second MZI that modulates the intensity of the second output light from the first coupler and outputs a fourth output light; a second coupler that combines the third output light from the first MZI and the fourth output light from the second MZI, branches a combined light into two, and outputs a fifth output light and a sixth output light. The interaction length of a branch of the first coupler and that of the second coupler are set such that the wavelength dependence of the splitting ratio of the first coupler is inversely related to that of the second coupler.
