Then we investigate the temperature and strain responses of FBGs in PMFs.
接着，研究了三种保偏光纤光栅温度和应变传感性质。
Fast axis of panda and bow-tie PMFs is more sensitive to temperature than slow axis, while slow axis has higher sensitivity to strain than fast axis.
熊猫型和领结型保偏光纤快轴的温度灵敏度大于慢轴，而应变灵敏度快轴小于慢轴。
The numerical results show that the modal birefringence of near_rectangle core PCF is at least one order of magnitude higher than the conventional elliptical polarization_maintaining fibers (PMFs).
