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 periodic structure can be configured by using interfaces or/and media within a stack. The user interface to set up the geometry of a stack is user friendly and allows to generate even more complex gratings easily. In this use case the investigation of the polarization state of the diffracted orders is discussed, which is enabled by the FMM.
