As optical systems become more complex, virtual validation of product performance through simulation from nano level to system level becomes increasingly important.
To address this challenge, many solutions have been developed using Speos and Lumerical to allow engineers to consider effects from nano scale to macro scale and analyze the full system using Maxwell's equation-based simulation and ray tracing simulation.
