Abstract

See full text

An optical waveguide device module includes an optical waveguide device and a connection substrate provided outside the optical waveguide device, and these are housed in a housing. The optical waveguide device has a control electrode including a signal electrode and ground electrodes disposed to interpose the signal electrode between the ground electrodes. A signal line, ground lines disposed so as to interpose the signal line between the ground lines, and a back surface ground electrode disposed on a surface of the connection substrate are provided on the connection substrate. The ground line and the back surface ground electrode are electrically connected through a via hole passing through the connection substrate. Electrical connection means for electrically connecting the ground line and the ground electrode is provided. A connection portion of the electrical connection means on the ground line side is in the vicinity of the via hole of the ground line.
