| Abstract: | A novel photonic crystal fiber with high birefringence and low confinement loss is designed,which can be used for chemical sensing.The effects of air holes parameters on optical properties of optical fiber are system?atically investigated.The results reveal that the relative sensitivities of the fiber with the optimal structure for wa?ter,ethanol and benzene at the wavelength of 1.55μm are 56.3%,59.9%and 62.5%,respectively.Compared with the existing PCFs,they are improved by 1.05-6.25 times,1.05-4.99 times and 1.03-4.63 times,respec?tively.Besides,it has excellent transmission characteristics.Therefore,the proposed photonic crystal fiber has advantages in chemical sensing and biomedicine filed. |
