Modeling of VCSEL Source by Two Uncorrelated Laguerre-Gaussian Modes

Vertical cavity surface emitting laser (VCSEL) diodes are of interest for numerous applications, such as optical sensors and pattern generators. In order to be able to investigate these kinds of setups in VirtualLab Fusion, an appropriate source model is required. In this use case, we demonstrated how to achieve the desired intensity distribution of a specific VCSEL source via parametric optimization of two uncorrelated Gaussian modes with the help of the multiple light source.
