Abstract :
The analytical form of the discretization error in modal calculations using the finite-difference method (in both one and two dimensions) has been derived. Based upon this knowledge, a linear extrapolation scheme is devised such that highly accurate propagation constants can be extracted from calculation results using coarse grids. Efficiency and precision are both improved significantly as a result
