Optical modeling software is critical for the photonics industry when designing new products or optimizing existing products. Junonia Photonics has developed an optical modeling suite of programs that are now being offered for the first time with presentation quality graphics built-in. The programs calculate optical properties of multilayer planar thin film stacks, multilayer conformal thin films on diffraction gratings, multilayer planar waveguides, general waveguides including strip and rib waveguides, astigmatic lens focusing, Mie scattering from multiple spherical shells, optical fibers with multiple concentric cylindrical shells, and scattered field finite difference time domain modeling. Check out the example calculations that can be done with our software on this website. For a limited time the software is available on eBay (link) at an extremely low introductory price.
