摘要
用差分方程法和直接积分法求扩散型平面光波导问题的解,得到了有10位有效数字的传播常数。证明在此问题上,差分方程法的简单计算比有限元法和其它方法更为优越。它是用自洽场法解通道光波导问题的数学基础之一。
The diffused planar light waveguide
problem is solved by using the difference equation method and the direct integration method,
and propagation constants with 10 significant figures are obtained. It is proved that a simple
difference equation calculation in this problem is superior to the finite element method and the
others. It is one of the mathematical foundations of self consistant field method to solve the
channel waveguide problem.
