Propagation through Multimode Fibers

[July 22, 2021]
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.

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.

Polarization and Fully Vectorial Physical Optics with VirtualLab Fusion

[June 25, 2021]
One of the most widely recognized advantages of physical optics as a simulation technology is the breadth of information it can provide about a system. The vectorial nature of the electromagnetic field, and the very often complex effects that arise from it as the light propagates in a system, are no small part of this consideration. That is why in VirtualLab Fusion we always work with the full vector field information.

Personalization through Global Options

[June 18, 2021]
To accommodate the variety that naturally exists in personal preferences, as well as to cater to the different specifications of the computing hardware available to each of our users, VirtualLab Fusion provides tools to tailor its configuration to your individual circumstances. Below we demonstrate how to personalize two different groups of settings in the Global Options: on the one hand, those pertaining to the graphic display of data and general visualization; on the other, performance related parameters related to the specifications of the computer which is running VirtualLab Fusion.

Focal Region Investigation

[June 18, 2021]
As an example, in the case of focusing with a high-NA objective lens, the focal spot is known to show asymmetry, and consideration of the vectorial nature of light turns out to be necessary. VirtualLab’s representation of light as an electromagnetic wave in a fully vectorial approach enables the analysis of these polarization-dependent effects in detail. Moreover, the properties of light in the focal region can be thoroughly investigated with the help of different detectors. In combination with the Parameter Run feature the field evolution through the focal region can be analyzed as well.
[June 18, 2021]

Lenses are, among all optical components, probably the most widely used, and focusing of light is possibly the most typical task in optics. Although it can seem trivial, the behavior of light in a focal region can be complex and is therefore worthy of in-depth investigation. As an example, in the case of focusing with a high-NA objective lens, the focal spot is known to show asymmetry, and consideration of the vectorial nature of light turns out to be necessary. VirtualLab’s representation of light as an electromagnetic wave in a fully vectorial approach enables the analysis of these polarization-dependent effects in detail.

Fabrication Export

[June 11, 2021]
We show that VirtualLab Fusion can export fabrication data for smooth as well as for quantized surfaces in various different data formats, which are commonly used by manufacturing techniques like 3D printing, computer-aided manufacturing or lithographic exposure techniques.
[June 11, 2021]

For the design of various optical components, like freeform surfaces, HOEs or DOEs, an important step in the workflow is the export of the generated data for subsequent manufacturing. In the examples below we show that VirtualLab Fusion can export fabrication data for smooth as well as for quantized surfaces in various different data formats, which are commonly used by manufacturing techniques like 3D printing, computer-aided manufacturing or lithographic exposure techniques.

Cross-platform Optical Modeling and Design (MATLAB & Python)

[June 03, 2021]
The physical optics software VirtualLab Fusion is constructed as a platform to combine different in-built and customized field solvers to enable fast physical-optics simulation and design with ray tracing naturally embedded. This multi-solver concept is complemented by the possibility to use a cross-platform approach, where VirtualLab Fusion is accessed externally.
[June 03, 2021]

The modeling and design of modern optical systems, with their increased complexity, can benefit from the combination of multiple software tools. Especially for optimization and data processing a single software package often cannot provide all the necessary functionalities in all fields of interest. The batch mode of VirtualLab Fusion, when used alongside other software tools, enables precisely this type of cross-platform simulations. As examples, we demonstrate how to use Python and MATLAB to access the field solvers from VirtualLab Fusion, and to perform analysis and optimization tasks on that basis.
