Unpolarized Light for Grating Simulation – Discussion at Examples

Optical devices like gratings are sensitive to the polarization of the light. Thus, it is important to properly consider the polarization of light in the simulation. In practice, gratings sometimes work with unpolarized light as input. We show how to model such unpolarized light, as the average of two orthogonal polarization states, for grating simulation in VirtualLab Fusion. Examples are provided to illustrate the corresponding settings in the software.
