Aberration Effects on Focused Modes from a Fiber Source

Fibers are widely used as sources in optical systems. Investigating the effects of the aberrations of an optical system on the propagation of the fiber modes is therefore of interest. In this use case we employ the fast physical optics engine in VirtualLab Fusion to demonstrate how the shape of a set of modes generated by either a step- or graded-index fiber, and the total field resulting from their combination, is affected by propagation through an aberrated optical system.
