Blazed Grating Analysis by Fourier Modal Method
The Fourier Modal Method (FMM) can be used to analyze grating efficiencies rigorously. VirtualLab allows rigorous efficiency analysis for single simulations as well as for parameter variations.
In VirtualLab you can setup your grating system, perform the rigorous analysis, and present the results in different format (e.g. grating order collection, single values, …). In combination with the parameter run you can also scan a given parameter space to investigate the performance of the specified structure for different configurations. For the evaluation of the results of the parameter run, several evaluation tools are available to give you the best insight in your optical setup.
