Modeling of Graded-Index (GRIN) Multimode Fiber
Abstract
Multimode fibers made out of graded-index media are widely used in optical applications. To simulate light propagating through the fiber, VirtualLab Fusion implements an approach, which solves Maxwell equation in a fast manner and includes polarization crosstalk effect. The validity and advantages of the fast approach is shown by comparing with the result from the rigorous Fourier modal method (FMM) with perfectly matched layers (PMLs). This example is published in [H. Zhong, J. Opt. Soc. Am. A 35(4): 661-668].

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].
Tutorial
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.
