Summary: 
Power dependent coupling efficiency for a butt-joined configuration using nonlinear cladding is analyzed by the beam propagation method. This configuration is not so sensitive to the angular misalignment as well as the offset between coupled waveguides on condition that the input power is appropriate to assure the propagation of spatial soliton.
