Abstract
A disclosed optical waveguide element includes a cladding portion formed on a substrate; an optical waveguide which is formed inside the cladding portion and has a refractive index higher than that of the cladding portion; an optical filter which is inserted into a slit formed in the cladding portion to divide the optical waveguide into a first optical waveguide and a second optical waveguide; and a first thin film element which is inserted into the slit along with the optical filter and is provided with a first thin film lens, wherein the first thin film lens provided in the first thin film element converges light that has propagated through the first optical waveguide and outputs into the slit into the second optical waveguide.
