Construction and Modeling of a Graded-Index Lens
Abstract
VirtualLab Fusion allows the specification of a graded-index lens in a very user-friendly way. In addition such index modulated lenses can be analyzed by ray tracing as well as field tracing. Within this tutorial we will show how easy it is to configure a graded-index lens in VirtualLab Fusion and show also simulation results for analysis by different propagation engines.
For the illustration of this technology a simple setup is used, which includes a spherical wave, a graded-index lens component and a detector to show the electromagnetic field component in the focus and directly after the lens.

Use Case
Gaussian Beam Focused by a Thermal Lens
This use case shows the variation of the focal length of the thermal lens, as well as the focus beam diameter when the input power changes [W. Koechner, Appl. Opt. 9, 2548–2553 (1970)]. This example is published in [H. Zhong, J. Opt. Soc. Am. A 35].
Use Case
Modeling of Graded-Index (GRIN) Multimode Fiber
A fast approach for light propagation through a GRIN medium, which includes the polarization crosstalk effect, is implemented, and its validity and advantages are shown in comparison with a rigorous solver.
