Summary on Grant Application Form
This Advance Fellowship (5 years) has been awarded and is due to commence october 1995. The proposed research is to intially to develop a comprehensive model to calculate second-order optical nonlinearities and related effects for semiconductor heterostructures. These have applications for wavelength and conversion and all-optical seitching. Subsequently, optimisation studies will be performed with a view to producing realistic device designs.The starting point for these calculations are semiconductor bandstructure models. Even before the extension to the determination of the nonlinear optical coefficients, these bandstructure calculations are often numerically intensive. As the model evolves to include effects of interest and particularly for the optimisation studies, powerful, dedicated computer facilities will be required. The University of Glasgow does have several Unix workstations but these are (1) for general use by undergraduate and postgraduate students and by university staff and (2) are generally show a much poorer floating point performance thatn the currently available RISC machines. The intensity of the numerics means that it is crucial to the progress of this research to be able to have sole use of a reasonably high performance computer.It is proposed to purchase for this project a Sun sparcstation 20/61 (SPECfp92 107.2) which is currently available at a 50% academic discount and offers the best value for the size of grant available. This will allow compatibility with existing workstations in the Department of Electronics and Electrical Engineering. It is intended that the algorithms be developed in Fortran and Mathematica programming languages. Fortran compliers and numerical libraries (e.g. Nag) are available at no extra cost (University Site Licence). However, the University does not have a site licence for Mathematics and its requested that a single machine copy is purchased for analytic and numerical bandstructure calculations.
