Abstract :
Long-period fiber gratings can be applied in several optical devices, such as mode converters, gain equalizers for optical fiber amplifiers, and band rejection filters. In order to design long-period gratings, a mathematical model has been developed, based on the coupled-mode theory, which takes into account different refractive-index profiles of the gratings and of the fiber
