摘要

光子晶体光纤（PCF）具有压力敏感特性。文章根据弹光理论推导了PCF应变与应力的关系

得到压力作用下PCF折射率分布波动的定量关系

提出一种微弯压力PCF传感器的设计方案

并从理论上分析了压力存在条件下光脉冲在PCF中传播时的相位波动及这种传感器的检测原理。

Abstract

The Photonic Crystal Fiber（PCF）is pressuresensitive.In this paper

the relationship between the strain and stress in PCF is deduced by elasto-optical theory and the quantitative fluctuations of its refractive index distribution under pressure obtained.The schematic design of a microbend pressure PCF sensor is presented and the phase fluctuation of the optical pulses transported in PCF under pressure and the detecting principle for such a sensor are theoretically analyzed.
