Higher-order wide-angle split-step spectral method for non-paraxial beam propagation.
We develop a higher-order method for non-paraxial beam propagation based on the wide-angle split-step spectral (WASSS) method previously reported [Clark and Thomas, Opt. Quantum. Electron., 41, 849 (2010)]. The higher-order WASSS (HOWASSS) method approximates the Helmholtz equation by keeping terms up to third-order in the propagation step size, in the Magnus expansion. A symmetric exponential ...
متن کاملEfficient Interface Conditions for the Finite Difference Beam Propagation Method
It is shown that, by adapting the refractive indexes prerequisite for the use of the FDBPM algorithm. We remark in the vicinity of interfaces, the ZD-beam propagation method based On the finite difference (FDBPM) scheme can be made much more effective. This holds especially for TM modes propagating in structures with high-index contrasts, such as surface ;hat the introduction of the adapted ind...
متن کاملModal Fields Calculation Using the Finite Difference Beam Propagation Method
A method is described to construct modal fields for an arbitrary oneor two-dimensional refractive index structure. An arbitrary starting field is propagated along a complex axis using the slowly varying envelope approximation (SVEA). By choosing suitable values for the step-size, one mode is maximally increased in amplitude on propagating, until convergence has been obtained. For the calculatio...
متن کاملWide-angle split-step spectral method for 2D or 3D beam propagation
We develop a method for non-paraxial beam propagation that obtains a speed improvement over the Finite-Difference Split-Step method (FDSSNP) recently reported by Sharma et al. The method works in the eigen-basis of the Laplace operator ∇2 T ) , and in general requires half as many operations to propagate one step forward so that a 2X speedup can be realized. However, the new formulation allows ...
متن کاملA three-dimensional non-paraxial beam propagation method using complex Jacobi iteration
A new complex Jacobi iterative technique adapted for the solution of three-dimensional (3D) non-paraxial beam propagation is presented. The beam propagation equation for analysis of optical propagation in waveguide structures is based on a novel modified Padé(1,1) approximant operator we recently proposed. The effectiveness of our new approach is demonstrated in comparison with the traditional ...
