【摘要】 用一级微扰理论，对二次多项式折射率分布平面光波导，进行了波方程的解析求解，推得用Ａｉｒｙ函数表示的场解和色散方程．用一级微扰近似计算了传播常数，并与实验值进行了比较，其结果是符合的．更多还原

【Abstract】 For the planar optical waveguide with second order polynomial index profile,the wave equation is solved by means of first order perturbational method in this paper,and analytical solution of mode field and mode dispersion equations are oblained in termsof Airy functions. The propagation constauts are calculated by the first orderperturbational approximation and compered to experimental values. The calculatedpropagation constants agree quite well with measured ones.更多还原
