(a) and (b) are the core-cladding interface with a square shape at the up and down boundaries. The maximum value of roughness is 7.5 nm (c), the variation of probabilities obtained by coupled mode equations. (d) The variation of probabilities obtained by FEM. (e) 2 d 2-dimensional view of wave propagation.
