Abstract

The development of photonic multi-scale devices with tailor-made optical properties requires the control and the manipulation of light propagation within structures of different length scales, ranging from sub-wavelength to macroscopic dimensions. On the other hand applications of common optical simulation methods are usually restricted to particular size regimes. Therefore a complete optical simulation of multi-scale devices requires the combination of different simulation methods. Simulating the light propagation both in the sub-wavelength regime and at macroscopic length scales in a combined simulation process can only be achieved by bridging between different simulation approaches, whose joint fields of application are capable to cover the whole spectrum of length scales. For this purpose well-defined criteria for a switching between different simulation methods are needed, in order to ensure mathematical and physical consistency of the simulation and to avoid a summation of errors due to the interfacing process.
