| 摘 要： | 分析了双空芯光子晶体光纤(HC-PCF)在纤芯填充液态高折射率温敏物质后的传输特性,应用全矢量有限元法(FEM)研究温度均匀变化时光纤耦合特性、模间色散特性的变化规律。结果表明,在特定温度下,耦合特性随传输波长的增大呈现出先减弱、后增强的变化趋势,且光纤的模间色散存在过零点。通过调节温度或占空比,可以在1.31μm和1.55μm两个常用通信波段内实现零模间色散传输,由此能够完全消除模式间相位不匹配导致的脉冲失真,实现能量的完全交换。 |

| Abstract: | A hollow dual-core photonic crystal fiber (HC-PCF) filled with high refractive index liquid sensitive to temperature is analyzed. The coupling properties and the inter-model dispersion are investigated by using full-vector finite element method (FEM). Theoretical results show that with the increase of the wavelength, the coupling coefficient will decrease first and then increase for a certain temperature. Especially, the zero inter-modal dispersion can be achieved at a particular wavelength. By adjusting the temperature and/or the structure parameter d/Λ, zero inter-modal dispersion in an extremely wide wavelength range including both 1.31 μm and 1.55 μm is realized. This implies that the pulse distortion effect due to the mismatch between different modes can be eradicated and 100% power transfer can be realized in such a hollow dual-core photonic crystal fiber. |
