提出了一种高效的非迭代三维全矢量光束传播法。在该方法中,表征器件全矢量特性的偏振耦合项被引入光束传播方程,并使用新型的交替方向隐式进行高效处理。数值模拟的结果表明,相比于传统的迭代方法,该方法在保持较高精度的同时,计算效率有了显著的提高。 An efficient non-iterative three-dimensional full-vector beam propagation method is proposed. In this method, the polarization-coupled terms that characterize the full vectorial behavior of the device are introduced into the beam propagation equation and implicitly processed efficiently using the new alternating direction. The numerical simulation results show that compared with the traditional iterative method, this method can improve the computational efficiency while maintaining high accuracy.
