Grating Analysis and Smoothly Modulated Grating Parameters on Lightguides
In order to control the uniformity and efficiency in a lightguide device for AR/MR applications, it is necessary to vary grating parameters, such as fill factor and grating height, over certain areas, e.g. in the expansion and outcoupling grating regions. For this purpose, VirtualLab Fusion enables the introduction of smoothly varied grating parameters inside one region, where the desired variation can be configured in very different ways. This also includes a tool to investigate the provided diffraction efficiencies for the specific incident conditions and grating parameters. This example explains, how to apply these tools.
