Analysis of Dual Overwritten Fiber Bragg Grating by Coupled-Mode Theory
The dual overwritten fiber Bragg gratings have significant applications in telecommunications and fiber sensors. The perturbation to the refractive index by dual overwritten fiber Bragg grating is analyzed, and the coupled mode equations are obtained. The spectral characteristics of dual overwritten fiber gratings are discussed and investigated by numerical simulation. The method described is conducive to the fabrication and applications of dual overwritten fiber Bragg grating.
