摘要

通过在微结构聚合物光纤(mPOF)的包层空气孔中填充液晶材料获得了高度热可调的带隙型mPOF. 带隙随温度的增加发生显著的蓝移, 带隙上边界的温度灵敏度可达-5.5 nm/℃. 采用全矢量有限元方法对模场特性以及基模有效模场面积的分析结果表明, 该填充液晶的mPOF在带隙的中心波长附近具有大的有效模场面积, 和相同结构未填充液晶的mPOF连接时具有较高的功率耦合效率. 研究结论为mPOF在温度传感领域的应用及各种可调光纤器件的制备提供了理论参考.

Abstract

A highly tunable bandgap-guiding microstructured polymer optical fiber (mPOF) is designed by infiltrating the cladding air holes with a liquid crystal. Bandgap is blue shifted as temperature is increased. A high thermal tuning sensitivity of -5.5 nm/℃ is achieved at the long-wavelength edge of the bandgap. Mode properties and effective mode area of the fundamental mode are investigated by using the full-vector finite element method. The designed fiber has a large effective area and high power transmission coefficient between the index guiding modes and the bandgap guiding modes. Our results provide theoretical references for applications of mPOF in sensing and tunable fiber-optic devices.
