Abstract

In this paper, some properties of optical fiber have been studied numerically by changing the values of graded-index as non-integer numbers using the finite element method (FEM) in the COMSOL environment. The results showed that the small graded orders gives a strange properties, such as a great value at nonlinearity and a new forms of dispersion relation are obtained. The paper enables us to choose the graded order and wavelength to achieve the desired values of dispersion and nonlinearity.
