    摘要:

    本文提出了一种可用于化学传感的具有高双折射、低损耗的光子晶体光纤,并系统地分析了空气孔参数对光纤光学特性的影响。研究表明,最优结构的光纤在典型波长1.55 μm时对水、乙醇和苯的相对灵敏度分别可达56.3%、59.9%和62.5%,相比现有光子晶体光纤分别提高1.05~6.25倍、1.05~4.99倍和1.03~4.63倍。此外,该光纤还具有较好的传输特性。因此,本文提出的光子晶体光纤在化学传感和生物医学领域方面更具优势。

    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 systematically investigated. The results reveal that the relative sensitivities of the fiber with the optimal structure for water, ethanol and benzene at the wavelength of 1.55 μm 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, respectively. Besides, it has excellent transmission characteristics. Therefore, the proposed photonic crystal fiber has advantages in chemical sensing and biomedicine filed.
