This paper demonstrates the spectrums of a long period fiber grating pair (LPGP) by changing the following physical parameters: the separation of the LPG, the length of single LPG and the number of single LPG .The study of the response of the LPGP to different parameters enables a rational design of the sensor element. These results produce an important foundation of our further study of LPGP spectral...
