摘要：An optical waveguide and a first lens are formed on an underlying surface. Theoptical 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 opticalwaveguide and diverging along directions parallel to the underlying surface. A secondlens converges light transmitted through the first lens and diverging along directionsperpendicular to the underlying surface. A support member supports the first andsecond lenses. It is possible to prevent a shift of positions of the optical waveguide andlens to be caused by a temperature change and to prevent a light coupling efficiencyfrom being lowered.
