Abstract:
1. An optical waveguide device comprising: a waveguide core that guides light; a mirror surface that deflects light coming from the waveguide core, wherein the mirror surface is formed of a single planar surface within a single plane, is irradiated by the light coming from the waveguide core, and is not wavelength-dispersive; a main waveguide core that guides a first part of the light deflected at the mirror surface; a waveguide core for monitoring that guides a second part of the light deflected at the mirror surface in a different direction from the main waveguide core, wherein the mirror surface is disposed at a common branching portion of the waveguide core, the main waveguide core and the waveguide core for monitoring; and a clad portion that surrounds the waveguide core, the main waveguide core, and the waveguide core for monitoring.
