The full-vectorial finite-difference method has been improved for solving mode loading problem on irregular ports, and the boundary conditions are derived. The new mode solver reduces the demand for computing resources: it can solve waveguide mode with arbitrary shape. The mode characteristics of waveguide with different shape are calculated;the results are compared to analytical solutions and those obtained from commercial software, they agree well with one another.
