Abstract

A third-order grating coupler with a grating period 3 times that of a first-order grating is discussed in terms of efficiency enhancement. A reflection film is integrated between the optical buffer layer and the substrate beneath the grating–guiding core. The power-distribution ratio for each diffracted wave depends on the optical buffer layer’s thickness because of interference effects. The thickness is determined to suppress first- and second-order diffraction and to enhance the power distribution to the output air-radiation wave generated by third-order diffraction. A demonstrator was designed and examined at a wavelength of 0.82 µm. The measured output coupling efficiency was 40%, whereas the theoretical prediction was 60%.
