ABSTRACT:
An optical waveguide and a first lens are formed on an underlying surface. The optical waveguide guides light along a first direction. The first lens is continuous with one end of the waveguide and converges light radiated from the end plane of the optical waveguide and diverging along directions parallel to the underlying surface. A second lens converges light transmitted through the first lens and diverging along directions perpendicular to the underlying surface. A support member supports the first and second lenses. It is possible to prevent a shift of positions of the optical waveguide and lens to be caused by a temperature change and to prevent a light coupling efficiency from being lowered.
