ABSTRACT:
The present invention relates to an optical modulator capable of preventing a disconnection of an electrode and improving a discontinuity of a characteristic impedance while realizing a polarization inverting area and a ridge waveguide in a single optical modulator. In the optical modulator, a first electrode is composed of an inverting area electrode portion formed on an upper portion of one of first and second waveguides in the polarization inverting area, a non-inverting area electrode portion formed on an upper portion of the other one of the first and second waveguides in the other area, and a connection portion for making a connection between the inverting area electrode portion and the non-inverting area electrode portion at the boundary between the polarization inverting area and the other area. A supporting mechanism for supporting the connection portion of the first electrode is provided in a groove.
