摘　　要：提出了一种新型的边孔型HB-PCF(高双折射光子晶体光纤),数值结果表明它在自由空间波长λ=1.55μm处的相位模式双折射达到了2.916×10-3,静态液体压力的相位模式双折射灵敏度高达-2.444×10-5 MPa-1,能够测量的静态液体压力最大值为119.3MPa。此外,这种边孔型HB-PCF具有极低的温度灵敏度,因此能实现静态液体压力的高性能测量。A novel side-hole Highly Birefringent Photonic Crystal Fiber（HB-PCF） is proposed.Its phase modal birefringence at 1.55 μm in free space is as large as 2.916×10-3,the sensitivity of its phase modal birefringence to hydrostatic pressure is as high as-2.444×10-5 MPa-1 and the maximum measurable hydrostatic pressure value is 119.3 MPa.In addition,with ultra-low sensitivity to temperature,it is believed to be an excellent candidate for future applications in hydrostatic pressure measurement.
