Summary on Grant Application Form
The program concerns spatial solitons on single surfaces and in multilayered waveguides. Mathematical models will be developed, backed by one and two- dimensional beam propagation programs, to study soliton coupling in strategic materials such as layered systems. As a top priority, imperfect waveguides will be analysed to include input/output coupling bending, impurity scattering, quantum effects, radiation noise and fluctuations in index and guide thickness which changes the coupling coefficient in soliton interactions. Guide-to-guide coupling problems will be treated with a general coupling formalism which is non-trivially different from the currently accepted Jensen model. Both space and time effects will be included to account for the complete space-time dynamics of soliton-bullet interactions and launching problems. The work includes the study of diffusion, attenuation -amplification inelastic interactions, counter-propagation effects and direction-dependent absorption. At the lowest priority the fascinating prospect of using magneto-optic materials will be investigated. It will be shown that the magnetic field provides a very useful extra degree of freedom: and it induces non-reciprocal propagation behaviour that can lead to unique control of the solitons. Several possible experiments to observe all the phenomena to be investigated will be simulated.
