Abstract
In order to independently perform control of a phase difference and a loss of light transmitting through an optical waveguide in a simple and easy configuration, an optical waveguide device includes an optical waveguide provided with two electrodes each supplied with a corresponding one of two signals; and a control unit for controlling the two signals so as to cause a phase variation and a loss variation which are caused in light transmitting through the optical waveguide by the two signals to each have a predetermined value.
