Improved Refractive Index Sensitivity Utilizing Long-Period Gratings with Periodic Corrugations on Cladding
A new structure of Long-Period Gratings (LPGs) sensor is introduced as a sensitive ambient RI sensor. This structure consists of creating periodic corrugations on the cladding of the LPG. The experimental results show that this LPG structure has good performances in terms of linearity and sensitivit...
