Abstract :
For clarifying the characteristics of cylindrical travelling wave in radial graded index dielectric and mode field of graded index fiber, the Helmholtz´s equation, local planar wave approximation, conservation law of radiant energy for travelling wave field and nonlinear effect for large electromagnetic field are engaged, a harmonic expression with nonlinear phase shift and additional phase shift is suggested as the travelling wave field in radial graded index dielectric approximately. And the linearly polarized mode method for step index fiber is used for reference, some novel expressions are proposed as the eigen functions of mode field in core layer and cladding layer of graded index fiber, and the eigen equation of graded index fiber. A similar linearly polarized mode solution of the graded index fiber is advanced.
