Abstract:
An optical modulator that suppresses the chirp due to the mask offset, for example during the phase modulation, and that provides a high waveform quality includes: two RF electrodes for applying one pair of differential signal voltages; at least one fixed potential electrodes for applying a fixed potential; a first conductive semiconductor layer and a second conductive semiconductor layer abutted to the RF electrode or a fixed potential electrode; and a light modulation unit including two optical waveguides branched from one optical waveguide that are arranged along a pn junction unit functioning as a boundary between the first and second conductive semiconductor layers, wherein: the semiconductor layers and the electrode are provided so that the integration amounts of the phase changes caused by the offsets of the positions of the pn junction units in the two optical waveguides from a design value is equal between the two optical waveguides.

Claim (Index 9):
An optical modulator, comprising: two RF electrodes for applying one pair of differential signal voltages; at least one fixed potential electrode for applying a fixed potential; a first conductive semiconductor layer and a second conductive semiconductor layer abutted to the RF electrode or the fixed potential electrode; and a light modulation unit including two optical waveguides branched from one optical waveguide that are arranged along a pn junction unit functioning as a boundary between the first and second conductive semiconductor layers, wherein:\n the modulation unit of the optical modulator has a first region positioned at the input side of a light propagation direction and a second region positioned at the output side, the connection of the first region and the second region has a structure having a multi-level crossing of the RF electrode and the optical waveguide in the same side, and the two optical waveguides both have the positional relation of the semiconductor doping status in the first region and the second region that is provided in a reversed position viewed in the light propagation direction in the respective optical waveguide, and one of the two optical waveguides is modulated by only one of the two RF electrodes.
