A Wide-Angle Full-Vector Beam Propagation Method Based on an ADI Preconditioner
Wide-angle full-vector Beam Propagation Methods (BPMs) for three dimensional wave-guiding structures can be derived based on rational approximants of a square root operator or its exponential (i.e. the one-way propagator). While the less accurate BPM based on the slowly varying envelope approximation can be efficiently solved by the Alternating Direction Implicit (ADI) method, the wide-angle va...

متن کاملThree-dimensional higher-order Padé approximant-based wide-angle beam propagation method using complex Jacobi iteration
Wide-angle scalar beam propagation methods (BPMs) for effective modelling of optical propagation in three-dimensional (3D) waveguides are usually limited to the low-order-accurate Padé(1,1) approximant. Presented is a 3D wide-angle scalar BPM based on higher-order Padé approximant operators which is factored into a series of simpler first-order Padé(1,1) approximants. This results in a multiste...
متن کاملWide-angle beam propagation method without using slowly varying envelope approximation
A new wide-angle (WA) beam propagation method (BPM) is developed whereby the exact scalar Helmholtz propagator is replaced by any one of a sequence of higher-order m ,n Padé approximant operators. Unlike the previous well-known WA-BPM proposed by Hadley [Opt. Lett. 17, 1426 (1992)], the resulting formulations allow one a direct solution of the second-order scalar wave equation without having to...
متن کاملFast three-dimensional generalized rectangular wide-angle beam propagation method using complex Jacobi iteration
A fast and efficient three-dimensional generalized rectangular wide-angle beam propagation method (GR-WABPM) based on a recently proposed modified Padé (1,1) approximant is presented. In our method, at each propagation step, the beam propagation equation is recast in terms of a Helmholtz equation with a source term, which is solved quickly and accurately by a recently introduced complex Jacobi ...
