System Modeling in K- and X-Domain

For an accurate and fast simulation of the propagation of light through complex optical systems, VirtualLab Fusion uses a “Connecting Field Solvers” approach that comprises the implementation of specific electromagnetic field solvers in both domains (space and spatial frequency). In this week’s newsletter we introduce the System Modeling Analyzer, a tool that allows the optical engineer to track the progress of the field (and its plane-wave spectrum) in detail as it propagates through their system. This can be incredibly useful for troubleshooting, as well as to gain additional insight into the behavior of a system. Additionally, we demonstrate the capabilities of VirtualLab Fusion to automatically select the best-suited Fourier transform algorithm wherever the operation is needed for the simulation, based on accuracy and computational effort criteria which can be adjusted by the user. We also show where to check which Fourier transform algorithms were selected. For more information, take a look at the use cases below!

In this document, the application and advantages of the System Modeling Analyzer tool are demonstrated at two different examples.

Automatic Selection of Fourier Transform Techniques in Free-Space Propagation Operator

VirtualLab Fusion provides a unified free-space propagation concept in the k-domain, together with an automatic selection of appropriate Fourier transform techniques.
