Modeling of Graded-Index (GRIN) Lens
Abstract
Graded-index (GRIN) media, with smooth variation of refractive indices, can be used to e.g. make a lens with flat surface, or reduce the aberrations. VirtualLab Fusion provides a physical-optics modeling technique for light propagation through GRIN media. With the same speed but far beyond ray tracing, the physical-optics modeling takes fully electromagnetic fields into consideration, which includes the polarization crosstalk effects.

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].

Construction and Modeling of a Graded-Index Lens
VirtualLab Fusion allows for 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 by field tracing.
