Abstract

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 1.5610^-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 -3×4 pm/°C/m and from 3.5 pm/με to 6.3 pm/με, respectively.
