摘要：
A planar optical waveguide including a clad layer, an optical waveguide having a core embedded in the clad layer; and a groove formed in the clad layer and having a reflection interface for totally reflecting a leaked light leaked from the optical waveguide to the clad layer. Since the reflection interface for totally reflecting the leaked light is formed in the clad layer, the leaked light is prevented from entering into the tap coupler, and the variation of the branching ratio can be reduced.
