LightTrans International, a developer of optical simulation software and photonics engineering solutions, offers VirtualLab Fusion, a software platform designed for physical optics modeling, laser system simulation, and advanced optical engineering applications. The platform combines wave optics, ray optics, and electromagnetic field analysis within a unified simulation environment to support the development of complex photonic and laser systems.
VirtualLab Fusion is built around the company’s Field Tracing technology, an approach that enables rigorous modeling of optical wave propagation through systems containing lenses, gratings, diffractive optical elements, freeform optics, fibers, and laser components. Unlike conventional ray tracing methods that primarily track geometric light paths, Field Tracing incorporates diffraction and interference effects, enabling more accurate simulation of modern photonic systems where wave-optical behavior is critical.
The software integrates multiple optical modeling techniques within a single platform, allowing users to combine ray optics, Fourier optics, physical optics, non-sequential propagation, and electromagnetic analysis in one simulation workflow. This hybrid modeling capability helps engineers evaluate complex optical interactions that occur in laser systems, imaging setups, micro-optics, and nanophotonic structures.
VirtualLab Fusion supports a wide range of applications including laser beam shaping, interferometry, holography, optical metrology, diffractive optics, microscopy, fiber optics, semiconductor photonics, and ultrafast laser system development. Engineers can simulate beam propagation, polarization effects, coherence behavior, and diffraction phenomena while analyzing system performance before hardware fabrication. The software platform includes dedicated modules for technologies such as grating design, diffractive optical elements (DOEs), micro-optics, freeform optics, and fiber coupling analysis. Users can model how light interacts with highly structured optical surfaces and photonic components, enabling optimization of beam quality, optical efficiency, and system functionality.
A major feature of VirtualLab Fusion is its support for laser source modeling and propagation analysis. The software allows simulation of Gaussian beams, partially coherent light, ultrashort pulses, and custom field distributions, supporting advanced analysis of resonators, beam delivery systems, and high-precision laser processing setups. This capability is particularly valuable for ultrafast photonics and precision laser engineering applications.
The platform also provides extensive visualization and analysis tools, including field intensity distributions, phase analysis, polarization visualization, propagation animations, and system performance metrics. These tools help researchers and engineers better understand optical system behavior and optimize designs for both scientific and industrial use. VirtualLab Fusion is used in industries and research areas such as laser technology, semiconductor manufacturing, optical communications, biomedical imaging, aerospace photonics, quantum optics, and academic research. The software supports both research-oriented investigations and industrial product development workflows requiring rigorous optical simulation capabilities.
LightTrans additionally emphasizes interoperability with other engineering environments and optical design workflows, enabling integration with CAD tools and external optical modeling platforms. This flexibility allows VirtualLab Fusion to fit into broader photonics engineering and product development processes. By combining wave-optical modeling, Field Tracing technology, and integrated photonics simulation capabilities, VirtualLab Fusion provides engineers and researchers with a comprehensive platform for the analysis and optimization of modern optical and laser systems.
