ABSTRACT:
The invention provides an optical modulator module by which a dip appearing in a frequency characteristic of a microwave from a DC component to a high-frequency component can be reduced while maintaining the mechanical strength and facilitating handling of a substrate and besides securing the long-term reliability without processing the substrate itself. The optical modulator module includes a substrate, an optical modulator including an optical waveguide, a signal electrode, and a ground electrode, and a housing in and to which the optical modulator is accommodated and secured. The shape of a longitudinal section of the other portion of the optical modulator module than the substrate is asymmetrical with respect to a perpendicular line with which the portion of the signal electrode which extends in parallel to the optical waveguide is bisected in the longitudinal direction.
