Robustness Optimization of a Slanted Grating |
| Time: 2026-01-13 20:58Source: infocrops.comWriter: infocrops |
Due to potential inaccuracies in the manufacturing process, it is essential for a good grating design to provide robust results in the face of slight variations in the grating parameters. VirtualLab Fusion offers the optical engineer various tools to incorporate this behavior directly in the optimization process, such as the Parameter Variation Analyzer. This tool combines multiple iterations of the same system, enabling the representation and automatic calculation of merit functions, like the mean efficiency, during optimization. In this use case we demonstrate this feature by optimizing a slanted grating with a slightly varying fill factor.
