摘要

采用Sagnac环干涉法研究了双折射光子晶体光纤(PCF)芯中氟(F)掺杂对温度和应变传感能力的影响。在1550 nm处测得f掺杂PCF的双折射率为1.56χ10−4，温度和应变灵敏度分别从- 9.6 pm/°C/m和3.5 pm/με增加到- 34 pm/°C/m。

Effect of F doping in the core of a birefringent photonic crystal fiber on sensing capability of temperature and strain sensors

Effect of fluorine (F) doping in the core of a birefringent photonic crystal fiber (PCF) on sensing capability of temperature and strain was investigated by using Sagnac loop interferometry. The birefringence of the F-doped PCF was measured to be 1.56χ10⁻⁴ at 1550 nm and the temperature and the strain sensitivities of the F-doped PCF were found to increase from −9.6 pm/°C/m to −34 pm/°C/m and from 3.5 pm/με to 6.3 pm/με, respectively.
