使用光纤法布里-珀罗 (FFP) 干涉仪和光纤布拉格光栅 (FBG) 测量了锗酸盐和亚碲酸盐玻璃纤维的应变和热敏感性。利用FFP干涉仪，在中心波长1540nm处，锗酸盐光纤和亚碲酸盐光纤的应变相位灵敏度分别为5900×103 rad/m和5600×103 rad/m，与锗酸盐光纤FBG的1.22pm/με值一致。锗酸盐和亚碲酸盐纤维的杨氏模量也测得为58GPa和37GPa。使用 FBG 在 1540 nm 和 1033 nm 波长下检查了锗酸盐光纤的热响应为 24.71 和 16.80 pm/°C。
Strain and thermal sensitivities of germanate and tellurite glass fibres were measured using a fibre Fabry-Perot (FFP) interferometer and fibre Bragg gratings (FBG). The strain phase sensitivity for germanate and tellurite fibre were 5900×103 rad/m and 5600×103 rad/m respectively at a central wavelength of 1540nm using FFP interferometer, which is consistent with the value of 1.22pm/με obtained for a germanate fibre FBG. The Young's modulus for germanate and tellurite fibre were also measured to be 58GPa and 37GPa. The thermal responses of germanate fibre were examined as 24.71 and 16.80 pm/°C at 1540nm and 1033nm wavelength using the FBG.
