Abstract: In this design we present a defected core photonic crystal fiber using borosilicate crown glass .This paper shows that how the central defected air hole ,controls the dispersion of a photonic crystal fiber .For this purpose ,Finite difference time domain (FDTD) method with the perfectly matched layers (PML) boundary conditions has been used to investigate the result. It is possible to have high negative dispersion, by varying the size of defected core. It is also shown that borosilicate glass PCF provides much higher negative dispersion as compared to silica PCF of the same structure, so such PCF have high potential to be used as a dispersion compensating fiber in optical communication.
