The dispersion is the parameter to investigate the performance of the PCFs similarly conventional optical fibers in the optical systems. This paper discusses several optimum designs wavelength ranging from 0.5 µm to 2.0 µm wavelength. In this paper we investigate the method for chromatic dispersion of Borosilicate crown glass from the scalar effective index method using transparent boundary condition with linear and elliptic waveguide. The chromatic dispersion is evaluated based on the result obtained due to the influence of the PCF structure parameters deviation. It has been demonstrated that nearly zero dispersion is possible to achieve in a range from 1.5 to 2.0 µm wavelength.
