Qian Liguo, Shi Weihua, Zhao Yan, et al. A side-hole photonic crystal fiber for hydrostatic pressure measurement[J]. 2012,(1):35-37. DOI: 10.13756/j.gtxyj.2012.01.001.
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.
