| Abstract: | The relationship existed in the nonlinear coefficient, the geometry parameters and wavelength is derived when considering photonic crystal fibers of total internal reflection type with triangle cladding by calculating the effective refractive index. The curves showing the relation are given. The relations of the nonlinear coefficient are discussed. Theoretical support for photonic crystal fibers in nonlinear research and application is provided. |

| Keywords: | photonic crystal fiber nonlinear coefficient effective refractive index |
