LASER World of Photonics

Demand is on the rise within the optical sector and research landscape to incorporate simulations of micro- and nanostructure effects into otherwise large-scale systems. One reason behind this trend is the incorporation of optical elements featuring micro- and nano-scale architectures. Examples include fibers, gratings, diffractive lenses, and metalenses. Exploring image formation of tiny objects also takes us into a multiscale simulation scenario. This also applies when simulating the impact of scratches, roughness, or dust on optical systems. VirtualLab Fusion features cutting-edge technology for multiscale optical simulation, seamlessly integrating everything on one platform without the hassle of juggling various software tools.

VirtualLab Fusion provides advanced tools for designing and simulating light shaping systems, supporting applications such as laser beam shaping, fiber coupling, and tailored illumination. We explore two key concepts: pointwise and diffuser-type shaping, each with distinct advantages. Using VirtualLab Fusion, we design and analyze components like freeform surfaces, metasurfaces, diffractive elements, and diffusers for different light shaping scenarios. The analysis also proves deep insights that comprehensively guide the selection and refinement of optical elements. We present practical examples demonstrating how these techniques can be effectively applied.
