ABSTRACT:
An optical waveguide device includes a substrate having an electro-optical effect, an optical waveguide formed on the substrate, an electrode provided for the optical waveguide, a monitoring optical waveguide for guiding part of light outputted from the optical waveguide as monitor light, an attenuation section provided for the monitoring optical waveguide for attenuating the monitor light, and a light detection section for detecting the intensity of the monitor light guided by the monitoring optical waveguide and attenuated by the attenuation section.
