Abstract: Refractive index distribution of gradient index polymer optical fiber(GI POF) was simulated by Lorenz function and model of refractive index distribution was found firstly, which included three basic parameters: initial concentration, molecule bulk of dopant monomer and polymerization temperature. The refractive index distribution of GI POF adulterated by kinds of high refractive index dopant monomer in PMMA was predicted by the Lorenz function model. It was found that effect of dopant monomers refractive index on gradient index was larger than that of molecule bulk; adulterate efficiency of diphenyl sulfide(DPS) was the highest in kinds of inertia dopant monomers; and adulterate efficiency of vinyl benzoate(VB) was the highest in kinds of co polymerization dopant monomers.

Key words: Gradient index polymer optical fiber, Refractive index distribution, Lorenz function
