Diffraction Optics Simulation And Design From KJ Innovation
Description
The Grating Diffraction Calculator (GD-Calc®), authored by Ken Johnson, is a MATLAB-based software package for diffraction grating simulation. GD-Calc computes diffraction efficiencies and polarization characteristics (multi-order transmission and reflection) of line gratings, biperiodic gratings, and multilayer-stack gratings with any number of layers and materials (dielectric or metallic). All software, documentation, demo tutorials, and sample output can be viewed and downloaded from the above-linked Code Ocean code capsule.
A recently-developed successor to GD-Calc, based on more advanced algorithms, has new capabilities for modeling curved/tapered structures (cylinders, pyramids, etc.) without relying on the “staircase” approximation, and modeling of bi-anisotropic and inhomogeneous grating materials (e.g., magnetic, crystalline, holographic, gradient-index, etc.). The new code (provisionally titled the “Grating Simulation Toolbox”, GSim), is not yet fully productized but can be used for specific customer applications.
