Helmholtz non-paraxial beam propagation method: An assessment (2014)
Journal Article
Chamorro-Posada, P., & McDonald, G. (2014). Helmholtz non-paraxial beam propagation method: An assessment. Journal of Nonlinear Optical Physics and Materials, 23(4), https://doi.org/10.1142/S0218863514500404

We present a performance evaluation of a non-paraxial beam propagation method suitable for the study of Helmholtz solitons. The analysis aims to determine the accuracy limits of the numerical scheme in terms of the maximum propagation angle addressab...

Single interfaces and coupled-waveguide arrays: off-axis nonparaxial analyses (2014)
Presentation / Conference
McCoy, E., Christian, J., McDonald, G., Sanchez-Curto, J., & Chamorro-Posada, P. (2014, September). Single interfaces and coupled-waveguide arrays: off-axis nonparaxial analyses. Presented at 5th European Optical Society Annual Meeting, Berlin, Germany

We report on our most recent results concerning arbitrary-angle spatial soliton refraction at the interface between dissimilar dielectrics, each of which comprises both X(3)and X(5) susceptibilities. Attention is also paid to the oblique injectio... Read More about Single interfaces and coupled-waveguide arrays: off-axis nonparaxial analyses.

Efficient parallel implementation of the nonparaxial beam propagation method (2014)

An efficient parallel implementation of a nonparaxial beam propagation method for the numerical study of the nonlinear Helmholtz equation is presented. Our solution focuses on minimizing communication and computational demands of the method which are... Read More about Efficient parallel implementation of the nonparaxial beam propagation method.

Widely varying giant Goos–Hänchen shifts from airy beams at nonlinear interfaces (2014)
Journal Article
Chamorro-Posada, P., Sánchez-Curto, J., Aceves, A., & McDonald, G. (2014). Widely varying giant Goos–Hänchen shifts from airy beams at nonlinear interfaces. Optics Letters, 39(6), 1378-1381. https://doi.org/10.1364/OL.39.001378

We present a numerical study of the giant Goos–Hänchen shifts (GHSs) obtained from an Airy beam impinging on a nonlinear interface. To avoid any angular restriction associated with the paraxial approximation, the analysis is based on the nonlinear He...
