Grating Optimization and Analysis

Gratings are some of the most fundamental tools in the arsenal of any optical engineer. To design and analyze this kind of component, the fast physical optics modeling and design software VirtualLab Fusion provides its users with many helpful tools. These include the Parametric Optimization, to easily optimize your systems, and the Parameter Run, which allows you to perform parameter sweeps in order to study the influence of those parameters on the overall behavior of the setup. Furthermore, this enables the use to investigate effects introduced by deviations due to specific fabrication processes in detail. Different solvers are also put at your disposal for the simulation of the interaction of the field with the grating, with different assumptions and the corresponding levels of approximation. These range from the rigorous Fourier Modal method (FMM) to the Thin Element Approximation (TEA), which works well for larger structures with a shallow relief.
