• birefringence effect
• SMF

The fabrication of LPFG in single mode fiber (SMF) was fabricated wing amplitude mask writing techniques. The birefringence effect of LPFG for sensing the transverse strain was discussed in detail. The experimental, results show that it exhibits a very high sensitivity and a good linearity to transverse strain, with a sensitivity,some hundred. times greater than what has been achieved using FBG sensor.
