Different from traditional treatment of solving wave equation
this paper analyzed mode mechanism in optical waveguide in the simple viewpoint based on the concepts of superposition of light waves
which generally used in general physics.The clear physical definition of waveguide mode is given.The field distributions in symmetry and asymmetry plane waveguide are calculated by the simple method from this viewpoimt
and the physical significance of characteristic equation and normalized frequency are also given.
