| Abstract: | Optimization structure of cladding radius and grating periods of long-period fiber grating(LPFG) was proposed,in order to achieve a high sensitivity of sensing the refractive-index of the external medium.Based on the coupled-mode theory of the LPFG,a theoretical analyzation was carried out between the cladding radius and grating period,and surrounding refractive-index,respectively.Effects of the variation of the cladding radius and grating period on the refractive-index sensing were discussed.Both of these ... |
