Description

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 will find GD-Calc and the accompanying documentation to be a very useful 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 MATLAB-based system simulation models. The code and documentation provide a wealth of 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.

Grating Diffraction Calculator (GD-Calc ®)

 

Grating Diffraction Calculator (GD-Calc ®) - Kenneth C. Johnson

GD-Calc is a MATLAB-based tool for diffraction grating simulation, which has utility for a variety of grating types and applications, e.g.:

 

- surface relief gratings

- multilayer gratings

- biperiodic gratings

- binary/lamellar or blazed kinoform gratings

- subwavelength gratings (e.g., photonic crystals, metamaterials)

- polarization gratings (e.g., form birefringence, wire-grid polarizers)

- moth-eye antireflection structures (e.g. for solar cells or high-power lasers)

- micro optics, nano optics, diffractive optics (e.g. phase-Fresnel structures)

 

Many illustrative applications of GD-Calc can be found in the peer-reviewed literature by searching for “GD-Calc” in Google Scholar. This code capsule is not directly linked to a publication but is provided as a computation utility for other publication-related capsules. References to background publications are cited in the demo scripts. (Note: Requires MATLAB version R2022a or later, will not run under Code Ocean's currently installed MATLAB versions.)
