Abstract

By using the coupled mode theory, the vector expressions of the core and the cladding electromagnetic field components of long-period fiber grating are analyzed. After the effective refractive indexes and the coupling constants of the core and cladding mode are solved, the transmission spectrum of the long-period fiber grating is obtained through solving the coupled mode equations by numerical integration method. The transmission spectra corresponding to single-mode and multi-mode are simulated, respectively. The research provides the theoretical foundation for the optimization design of the long-period fiber grating and its application in the field of the optic fiber sensing and communication.
