首次提出了一种用于位移、应变和高温传感的非绝热石英微光纤。微光纤的光谱响应依赖于纤芯和包层模的有效折射率之差，这引起谐振波长随应变和温度的偏移。观察到透射梳状谱的峰值波长以4.2pm/μ m的速率相对于位移发生蓝移。该器件的温度灵敏度为12.1 pm/℃，在高达800 ℃的温度测量中具有出色的线性度。(C)2013 Elsevier B. V.保留所有权利。
A non-adiabatic silica microfiber is proposed for displacement or strain and high temperature sensing for the first time. The spectral response of the microfiber depends on the difference of the effective refractive indices of the core and the cladding modes, which induces resonant wavelength shift against the strain and temperature. It is observed that the peak wavelength of the transmitted comb spectrum is blue-shifted against displacement at a rate of 4.2 pm/mu m. The temperature sensitivity of the device was measured to be 12.1 pm/degrees C with an excellent linearity for temperature measurement up to 800 degrees C. (C) 2013 Elsevier B.V. All rights reserved.
