Polarization and Fully Vectorial Physical Optics with VirtualLab Fusion

One of the most widely recognized advantages of physical optics as a simulation technology is the breadth of information it can provide about a system. The vectorial nature of the electromagnetic field, and the very often complex effects that arise from it as the light propagates in a system, are no small part of this consideration. That is why in VirtualLab Fusion we always work with the full vector field information.

Below you can find some illustrative examples that showcase the potential of VirtualLab Fusion in situations specifically related to polarization and vectorial effects.

Randomly Polarized Light for Grating Simulation at Examples

It is shown how to model the effect of unpolarized light in VirtualLab Fusion as the average of two orthogonal polarization states, using the simulation of grating systems as examples.

Confocal Scanning Microscope

This system illustrates the function of a confocal microscope using a grating as a sample. With the thorough vectorial treatment of the electromagnetic field in VirtualLab Fusion alongside its “connecting field solvers” approach, the initial field polarization, the faint cross-talk at the lens surfaces, the appearance of the longitudinal component due to the focusing behind the objective, as well as the strongly vectorial response of the grating are all automatically taken into account in the simulation in a seamless way.
