The polarization mode dispersion in highly birefringent photonic crystal fiber is measured. In the experiment, the differential group delay of 108 ps was obtained by using a 26-meter-long PCF. Furthermore, PMD in this PCF has been measured by pulse delay method and fixed analyzer method. The result shows that the birefringence of the PCF is about 1.25×10 -3, and the high birefringent PCF can be used as dispersion compensation component in optical fiber communication system.
