| abstract | An optical element that can be manufactured at a high yield and at a low cost and has improved element characteristics is provided. An active layer formed on a semiconductor substrate, a diffraction grating formed on the active layer, a semiconductor buried layer formed on the diffraction grating, and a semiconductor buried layer An optical waveguide through which light propagates is formed in the active layer in the region where the cladding layer is formed, and on the side surface of the cladding layer, A first embedded material layer is formed in the vicinity of the end of the optical waveguide, and a second embedded material layer is formed in the vicinity of the center of the optical waveguide. The above problem is solved by an optical element in which the refractive index of the material layer and the refractive index of the second embedded material layer are different.
