Abstract

We designed, manufactured and characterized two birefringent microstructured fibers that feature a 5-fold increase in polarimetric sensitivity to hydrostatic pressure compared to the earlier reported values for microstructured fibers. We demonstrate a good agreement between the finite element simulations and the experimental values for the polarimetric sensitivity to pressure and to temperature. The sensitivity to hydrostatic pressure has a negative sign and exceeds -43 rad/MPa x m at 1.55 microm for both fibers. In combination with the very low sensitivity to temperature, this makes our fibers the candidates of choice for the development of microstructured fiber based hydrostatic pressure measurement systems.

摘要

我们设计、制造并表征了两种双折射微结构光纤，与早期报道的微结构光纤相比，其对静水压力的偏振灵敏度提高了5倍。我们证明了有限元模拟与压力和温度偏振灵敏度的实验值之间具有良好的一致性。两种光纤在1.55微米处对静水压力的灵敏度均为负值，且超过-43 rad/MPa·m。结合极低的温度灵敏度，这使得我们的光纤成为基于微结构光纤的静水压力测量系统开发的首选候选材料。
