Grating Optimization for Desired FOV
Time: 2019-03-18 08:24Source: infocrops.comWriter: infocrops
Slanted gratings play an important role in modern waveguide-based near-eye display devices for AR/MR applications. In VirtualLab Fusion, the performance of slanted gratings can be rigorously analyzed with the Fourier modal method (FMM, also known as RCWA). And, in combination with the evolutionary algorithm from optiSLang, we show how to optimize the parameters of a slanted grating structure for user-specified targets, e.g. good uniformity over the desired FOV or high coupling efficiencies on average. 
 
Optimization of Slanted Grating for Lightguide Coupling
 
 
We optimize a slanted grating for waveguide coupling over the desired field of view (FOV), using VirtualLab Fusion and optiSLang in combination.
 
 
 
Advanced Configuration of Slanted Gratings
 
 
Coated slanted gratings can be configured easily in VirtualLab Fusion. This use case explains the available options for the customization of slanted gratings.
