In the areas of illumination and imaging the simulation of complex source models like light source arrays or extended sources is necessary for many different applications.
We therefore want to demonstrate a new feature from the latest VirtualLab Fusion release (2021.1) which enables the configuration of such kind of sources through the definition and combination of different source modes. The modes can be configured as coherent or incoherent to each other to allow for the modeling of either fully coherent, fully incoherent or partially coherent sources.Read more
In order to provide additional design freedom in terms of polarization control and multiplexing, in many applications anisotropic layers are attached to the surfaces of optical components.
As the birefringence effect depends strongly on the orientation of the crystal axis with respect to the direction of the incoming light, the discussion of such kind of components is especially interesting when the coating is applied to a curved surface.Read more
Birefringence and other polarization effects are a major part of any simulation of anisotropic optical components, which feature prominently in many applications, the fabrication of liquid crystal displays among them.
VirtualLab Fusion gives you the option to include anisotropic media in your system, in the form of coating layers or in different components, like the Stratified Media component or the Crystal Plate. This allows for a complete simulation of single and multi-layer polarizers as demonstrated in the examples below.
Anisotropic media, and crystals in particular, have long been linchpin components for various applications, including lasers and display technologies.
A HIGHLIGHT OF THE LATEST RELEASE, 2021.1
For the design, simulation and optimization of such kind of optical setups, VirtualLab Fusion provides a fast and rigorous electromagnetic field solver
that models the propagation of the electromagnetic field through anisotropic media, including polarization effects like conical refraction and birefringence.
Multimode fibers are an integral part of most optical communication technologies. For a sound modeling of such structures, accurate propagation of the fiber modes and their interference is necessary. In VirtualLab Fusion it is possible to use Bessel and Laguerre Polynomials to describe the fiber modes, for single-core fibers as well as graded-index ones. The resulting modes can then also be propagated while considering additional effects like e.g. atmospheric turbulence.Read more
