摘要
En 中文
A new 5-point finite difference operator is developed for integrated optics simulations. interfaces are taken into account accurately. The eigenvalues of the discretization matrix converge rapidly, according to O(Delta x(4)). Implementation of the operator in a beam propagator leads to a highly efficient computation scheme.
