The VirtualLab Fusion from LightTrans International is an Optical Design Software developed for multiscale optical simulation and design. It uses a unified platform with seamless interoperability between simulation models. This software provides a suite of simulation models tailored for a wide variety of optical components and structures, addressing all scales from tiny nanostructures to large optical systems.
The VirtualLab Fusion includes geometrical-optics techniques for lenses & freeform surfaces, the Rigorous Coupled Wave Approach (RCWA) for analyzing gratings, and the Fourier Modal Method (FMM) enhanced with Perfectly Matched Layer (PML) technology for nanostructures. It also features solvers for coatings & stratified media, specialized solvers for flat optics, and split-step methods for graded-index & microstructures. This software includes models for crystals, waveguides, and fibers, as well as simulation models utilizing BSDF data.
The VirtualLab Fusion enables the investigation of optical components and structures such as lenses, nano- and micro-scale structures, gratings, lens arrays, diffractive & holographic optical elements, metalenses, optical diffusers, GRIN lenses, coatings, scattering surfaces, polarizers & crystals. It autonomously connects different simulation models in a non-sequential manner for multiscale 3D optical system simulation. This software supports the modeling & analysis of optical systems involving interferometers, microscopes, Fourier optics setups, laser beam systems, AR/MR lightguides, ultrashort pulses, and sources such as lasers, laser diodes, VCSELs, LEDs & x-rays.
