Abstract

Photonic Crystal Fiber (PCF) is also called microstructure fiber. The PCF is filled with magnetic fluid, and the optical characteristics of the PCF can be tuned and sensed according to the adjustable characteristics of the refractive index of the magnetic fluid. In this paper, the influence of filling magnetic fluid (MF) on the transmission characteristics of the PCF is analyzed. Precisely, PCF mode field distribution, fundamental mode refractive index and loss characteristics were analyzed. Analyze the influence of temperature on the transmission characteristics of two types of PCFs. The simulation results showed that the mode field area of the circular holes PCF is about twice that of the elliptical holes PCF under the condition of 20°C. With the increase of temperature, the loss peaks of elliptical holes PCF and circular holes PCF both increase and redshift. The wavelength sensitivity and loss sensitivity of the circular holes PCF are higher than that of the elliptical holes PCF. This work provides a reference for designing high-sensitivity optical fiber sensor devices.

磁流体填充光子晶体光纤的传输特性

光子晶体光纤(PCF)又称微结构光纤。PCF内填充磁流体，根据磁流体折射率的可调特性对PCF的光学特性进行调谐和传感。本文分析了填充磁流体对PCF传动特性的影响。精确地分析了PCF模场分布、基模折射率和损耗特性。分析温度对两种聚氯乙烯传输特性的影响。仿真结果表明，在20℃条件下，圆孔PCF的模场面积约为椭圆孔PCF的两倍。随着温度的升高，椭圆孔PCF和圆孔PCF的损耗峰均增加且红移。圆孔PCF的波长灵敏度和损耗灵敏度均高于椭圆孔PCF。为设计高灵敏度光纤传感器器件提供了参考。
