摘要: 为了提高光子带隙型光子晶体光纤的温度灵敏度,提出了在纤芯环上并入高折射率液体圆柱的新结构,并利用全矢量有限元法对提出的结构进行了仿真,得到了温度对光纤有效折射率、纤芯能量和有效模面积等传输特性的影响。结果表明,随着温度的升高,光纤的有效折射率和有效模面积会减小,纤芯能量会增加,且零群速率色散点向短波长方向移动,尤其在短波长条件下光纤传输特性随温度变化趋势更加明显。该研究提高了光子带隙型光子晶体光纤传输特性的温度灵敏度,使其更加适合于温度传感方面的应用。

Abstract: In order to improve the temperature sensitivity of photonic bandgap fiber,a new structure was proposed merging high refractive index liquid cylinders into the surround of the fiber core.By means of full-vector finite element method,the influence of temperature on the effective refractive index,core energy,effective mode area was obtained.The numerical results show that when the temperature increases,the effective refractive index and the effective mode area decrease,the core energy increases,and the zero dispersion wavelength moves towards longer wavelength.These changes are quite significant when the wavelength is short.The proposed structure improves the temperature sensitivity of the transmission characteristics,which makes photonic bandgap photonic crystal fibers more suitable for temperature sensing applications. -
