Grating Diffraction Calculator (GD-Calc)

GD-Calc™, the Grating Diffraction Calculator, computes optical diffraction efficiencies of diffraction gratings and periodic structures comprising linear, isotropic, and non-magnetic optical media, based on a generalized variant of rigorous coupled-wave (RCW) diffraction theory. Engineers, scientific programmers, researchers, and students with an interest in optics can use GD-Calc and the accompanying documentation as a resource for diffraction grating analysis.

GD-Calc is implemented entirely in MATLAB^®, providing a convenient, user-modifiable interface, and making it easy to incorporate grating components in system simulation models based on MATLAB. The code and documentation provide technical and instructional information and computational capabilities for a broad range of grating types. GD-Calc is available online at no charge. KJ Innovation offers support and consulting services relating to customized simulation, design, and optimization of grating structures using GD-Calc and other more advanced software tools.

GD-Calc is available for download on Code Ocean.
