Abstract
A Y-branch type first interferometric modulator, and a coupler structure type second interferometric modulator are connected in cascade. The levels of DC bias voltages applied to the first and second interferometric modulators, respectively, are adjusted for maximizing the linearity of a modulated output light signal. The configuration of input and output coupler structures of the second interferometric modulator are predetermined for also contributing to maximizing the linearity of the output signal.
