Two-colour optical fields: modulational instabilities and vector spatial solitons (2011)
Presentation / Conference
Bostock, C., Christian, J., & McDonald, G. (2011, November). Two-colour optical fields: modulational instabilities and vector spatial solitons. Presented at 2nd CSE Doctoral School Postgraduate Research Conference, University of Salford, Greater Manchester

The propagation of a light beam at a single optical frequency – or colour – in a Kerr-type planar waveguide is an elementary configuration in photonics [1,2]. Under two classic assumptions: (i) that the transverse extent of the beam is much greater... Read More about Two-colour optical fields: modulational instabilities and vector spatial solitons.

Numerical investigations on nonlinear nonparaxial beam propagation using graphics processing units (2011)
Presentation / Conference
Chamorro-Posada, P., Sánchez-Curto, J., & McDonald, G. (2011, November). Numerical investigations on nonlinear nonparaxial beam propagation using graphics processing units. Presented at 8th Iberian Meeting on Computational Electromagnetics, Sesimbra, Lisbon, Potugal

We study the performance of a nonparaxial beam propagation method accelerated using massively parallel computation in graphic processing units. The implementation is tested in two different NVIDIA hardware architectures, Tesla and Fermi, and the resu...

Optical fractals: characterization, cavities, coherence and connections (2011)
Presentation / Conference
Mcdonald, G., Christian, J., Walsh, T., & Huang, J. (2011, September). Optical fractals: characterization, cavities, coherence and connections. Presented at 11th International Conference on Laser and Fiber Optics Networks Modeling, LFNM'2011, Kharkov, Ukraine

Uniform and regular systems can generate optical fractals. After characterizing different fractal-generating systems, emphasis is placed on the roles of boundary conditions and cavity feedback. New aspects of linear and nonlinear optical fractals are... Read More about Optical fractals: characterization, cavities, coherence and connections.

Spatial solitons and instabilities in two-colour Helmholtz light fields (2011)
Presentation / Conference
Bostock, C., Christian, J., & Mcdonald, G. (2011, August). Spatial solitons and instabilities in two-colour Helmholtz light fields. Presented at First Annual Student Conference on Complexity Science, Winchester University, UK

Two-colour optical beams comprise a pair of light waves at two well-separated temporal frequencies, and which are coupled through system nonlinearity (e.g., the Kerr-type response in the host material of a planar waveguide). In addition to their fund... Read More about Spatial solitons and instabilities in two-colour Helmholtz light fields.

Scattering of Helmholtz spatial optical solitons at material interfaces (2011)
Presentation / Conference
McCoy, E., Christian, J., & Mcdonald, G. (2011, August). Scattering of Helmholtz spatial optical solitons at material interfaces. Presented at First Annual Student Conference on Complexity Science, Winchester University, UK

The behaviour of light at the interface between different materials essentially defines the entire field of Optics. Indeed, the reflection and refraction properties of plane waves at the boundary between two dissimilar linear dielectrics are analysed...

Pulses with relativistic and pseudo-relativistic aspirations (2011)
Presentation / Conference
Lundie, M., Lancaster, G., Hodgkinson, T., Christian, J., Mcdonald, G., & Chamorro-Posada, P. (2011, July). Pulses with relativistic and pseudo-relativistic aspirations. Presented at Waves 2011 - 10th International Conference on Mathematical and Numerical Aspects of Waves, Vancouver, Canada

Temporal solitons are robust self-localizing pulses that play a pivotal role in modern understandings of nonlinear wave phenomena. Here, we propose a new approach for describing pulses in dispersive nonlinear systems. By retaining the fuller generali...
