严格耦合波法计算体布喇格光栅衍射效率
Calculation of diffraction efficiency of volume Bragg gratings with rigorous coupled-wave method
摘要
Abstract
In order to obtain the accurate diffraction efficiency of gratings, the diffraction mechanism of volume Bragg gratings was established and the diffraction efficiency was calculated with the rigorous coupled-wave method. The first-order coupled Maxwell' s equations was solved in terms of Legendre polynomials, and the diffraction efficiency of volume Bragg gratings was obtained. The simulation results were consistent with theoretical calculation results. This method converges faster than the matrix method, and is more precise than the Kogelnik coupling wave theory.关键词
