Abstract:
An optical waveguide module in which transmitted light emitted from a laser light-emitting element passes through a first optical waveguide and a second optical waveguide to strike a transmitting/receiving medium which is used for transmitting and receiving light, and in which a signal light from said transmitting/receiving medium passes through said second optical waveguide and is received by a light-receiving element, said optical waveguide module comprising:a first light-blocking resin, which covers a light-emitting coupling part that couples said laser light-emitting element and said first optical waveguide, and a second light-blocking resin, which covers a light-receiving coupling part that couples said light receiving element and said second optical waveguide; wherein the first and second optical waveguides are integrated optical waveguides disposed on a waveguide substrate, and wherein the light-emitting element and light-receiving element are disposed on opposite sides of the waveguide substrate.
