Abstract(in English) | A grating-assisted directional coupler made of two dielectric slab waveguides is analyzed by using coupled-mode formulation based on singular perturbation technique. The formulation is based on the para-axial wave fields for each isolated waveguide, and the effects of the adjacent waveguide and the grating are regarded as the perturbations. The coupled-mode equations are derived by the first-order and second-order perturbation analyses. The calculated wavelength response in the power transfer is in close agreement with that obtained by a direct numerical analysis using the Fourier series expansion method. |
