A Convolutional perfectly matched layer is employed as an absorbing boundary condition. Furthermore, we have established a rigorous formulation for estimating the modal power of each and mode. We confirmed the validity of the proposed method through the analysis of NRD crossing and T-branch guide devices. Excellent accuracy is achieved by the cross comparison of 2D-FVFDTD results with recently developed two-dimensional full vectorial finite element method.}, pages = {447--453}, title = {Analysis of NRD guide devices using rigorous two-dimensional full-vectorial FDTD method}, volume = {65}, year = {2022} }
