研究了在普通和缩小直径高双折射光纤中写入的光纤布拉格光栅。在测量FBG光谱的光学特性时，使用化学蚀刻来减小光纤的直径。所得结果与应力增强化学腐蚀定性一致。光纤的双折射率是作为直径的函数来确定的。横向应变和温度下的光纤光栅的光学特性也进行了。所获得的结果表明，这些参数的同时测量与HiBi光纤光栅传感器的可行性。
Fibre optic Bragg gratings (FBGs) written in normal and reduced diameter high birefringence (HiBi) fibres are studied. Chemical etching is used to reduce the diameter of fibres while the optical properties of the FBG spectrum are measured. The results obtained agree qualitatively with the stress enhanced chemical etching. The birefringence of the fibre is determined as a function of the diameter. Optical characterization of the FBG under transverse strain and temperature is also performed. The results obtained show the feasibility of the simultaneous measurement of those parameters with a HiBi FBG sensor.
