Abstract

Accurate modelling of photonic systems has to allow for the treatment of complex geometries and unusual material properties. While the former suggests the use of unstructured measures in conjunction with high-order basis functions such as in traditional finite element approaches, the latter implies working within the time domain so that general nonlinearities and transient phenomena can be considered. The Discontinuous-Galerkin Time-Domain (DGTD) represents a method that combines the sophistication of traditional finite element approaches regarding the spatial discretization with high-order time-stepping capabilities. Together with appropriate material models, the DGTD approach [1] thus represents a flexible methodology for the high-accuracy modelling of photonic systems.
