Configuration of Grating Structures with Two-Dimensional Periodicity
Abstract
Complex 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, also known as RCWA). With the graphical user interface, one can set up the geometry of a stack, so to generate complex grating structures.
This tutorial is focused on the configuration of grating structures which exhibit a two-dimensional periodicity.

Configuration of Grating Structures by Using Interfaces
In VirtualLab Fusion, grating structures are configured in a “stack”, which can be constructed with either a sequence of interfaces or special media, depending on the geometry of the grating.
