摘要：
An efficient butt-joined coupling scheme between single-mode planar waveguides with different refractive index profiles is proposed. The configuration consists of tapered waveguide with nonlinear cladding. Power dependent coupling efficiency of the configuration is analyzed by the beam propagation method. The numerical results show that this configuration has high-coupling efficiency and is less sensitive to the offset between coupled waveguides if the input power is properly selected.
