Mach-Zehnder Interferometer with Small Obstruction

Abstract

The accurate simulation of light fields that encounter small light-blocking objects during propagation, leading to additional diffraction effects that must be finely sampled, represents a classic multi-scale simulation challenge that is numerically demanding. VirtualLab Fusion enables highly computationally efficient simulations by decomposing light into separate modes. This use case demonstrates the impact of light being blocked at a small point in a Mach-Zehnder interferometer system, such as by an interfering particle on the sample surface.
