摘　　要：因为光线量子力学方程的光线哈密顿算符不表示能量，而是具有可变折射率的物理意义，因此应用光线量子论讨论波导中光场能量分布是一个有待研究的问题本文借鉴量子力学几率密度和几率密度矢量概念推导出光场能量分布的普遍性公式。We have researched field distribution of plane waveguide changing index waveguide and fiber by light ray quantum equation 2.Because Hamiltonian in light ray quantum equation is gradient index,thus energy distribution in light field must be researched by light ray quantum theory.This paper shows general formula of energy distribution of light field by using probability density and probability flow density vector of quantum mechanics.It also proves that energy in light field obeys conservation law
