摘　　要：给出一种差分法，用以求解任意折射率剖面的平板波导及圆光纤的本征方程。本法编程十分简单，不涉及特殊函数的繁复计算，有普适性，可精确求得色散曲线、截止频率与模场分布。A simple and efficient finite difference method is proPOsed to solve the eigenvalue equations for planar optical waveguides and circular fibers with arbitrary refractive index profiles. The compunction programs are simple and there is no need of explicitly evaluating Special functions. It can give accurate data for dispersion characteristics, cut-off frequencies and modal fields.
