Optical grating structures are widely used for several applications such as spectrometers, near-eye display systems, etc. VirtualLab Fusion provides rigorous analysis of arbitrary grating structures in an easy way by applying the Fourier modal method (FMM). In the Grating Toolbox, the grating structure can be configured by using various interfaces or/and media within a stack. The user interface to set up the geometry of a stack is user friendly and can be used to generate even more complex grating structures. In this use case the configuration of grating structures based on interfaces is explained.
