The fabrication of LPFG in single mode fiber (SMF) was fabricated using amplitude mask uriting 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.
