摘要

为了研制具有更高灵敏特性的温度传感器

文章提出利用光子带隙效应

在PCF（光子晶体光纤）中选择性填充热敏液体实现高灵敏温度传感。应用全矢量平面波展开法计算光纤带隙

带隙及其宽度随温度规律性漂移。当在包层空气孔中选择不同位置和结构填充热敏液体时

发现仅填充内层空气孔时

带隙随温度漂移造成的变化率最大。当在包层第一层空气孔中填充热敏液体

晶格周期Λ=9μm

空气填充率分别选取d/Λ=0.9和d/Λ=0.5时

带隙边界波长检测和带隙宽度检测的温度灵敏度分别可达到22.07和7.01nm/℃

具有精确度高和系统结构简单的优点。

Abstract

For the development of a temperature sensor with still higher sensitivity

this paper proposes to selectively fill thermosensitive fluid into the PCF by using the photonic bandgap effect so as to achieve highly sensitive temperature sensing.It calculates the bandgap using the full vector plane wave expansion method and the bandgap and its width drift regularly with temperature.When the thermosensitive fluid is selectively filled in the different locations and structures of the cladding air holes it is found that when only the inner air holes are filled

the variation caused by the bandgap with temperature drift is the maximum;When the 1st-layer air holes of the cladding is filled with the fluid

the lattice periodΛ =9μm and air-filling ratio are repectively selected as d/Λ = 0.9and d/Λ = 0.5

the temperature sensitivity in bandgap boundary wavelength detection and band-gap width detection can be 22.07 and 7.01nm/℃ respectively

which shows the advantages in high accuracy and simple system structure.
