Connecting Field Solvers demonstrated at Examples in VirtualLab Fusion

[March 31, 2021]
In this newsletter we show you how VirtualLab Fusion with its fast physical-optics technology allows for an inclusion of complex elements in the simulation of your optical system and enables the detailed analysis of relevant effects.
[March 31, 2021]

In modern optical systems very different kinds of elements are used in order to push the limits of our manipulation of light further and further. New elements are developed and traditional devices are steadily improved to obtain the desired functionality and performance, which not seldom increases the level of complexity of these components and the entire systems. VirtualLab Fusion with its fast physical-optics technology, that is based on the flexible and automatic connection of different field solvers, allows for an accurate modeling of your optical system and enables the detailed analysis of relevant effects.

Vector Beam Generation

[March 24, 2021]
In VirtualLab Fusion, the electromagnetic field propagation through an arbitrary system can be calculated as polarization and diffraction phenomena are automatically handled.
[March 24, 2021]

The vector beam is a beam that is fully polarized but shows different polarization states in different local positions on one detector plane. More specifically, if a polarizer is put after a vector beam, different energy density distributions will be recorded as the polarizer is rotated. Vector beams are widely utilized in many applications such as microscopy imaging or laser manipulation.  Using an interferometer with a vortex-phase spatial light modulator (SLM) and wave plates a vector beam can be generated. However, the modeling of the generation process needs precise handling of the vectorial behavior and diffraction of the electromagnetic fields. VirtualLab Fusion, a fast physical optics software platform, is the perfect choice to model such beams. In VirtualLab Fusion,  the electromagnetic field propagation through an arbitrary system can be calculated as polarization and diffraction phenomena are automatically handled.

Import of Microstructure Data via Bitmap and Material Data into VirtualLab Fusion

[March 18, 2021]
In this newsletter, we focus on the import of the height profile of a microstructure and of material data into VirtualLab Fusion.
[March 18, 2021]

In optical modeling it is of necessity to be able to replicate the real world setup as accurately and in as much detail as required. This means that the detail level of the model has to be high enough to account for all relevant effects. The proper setting-up of a digital twin therefore necessitates the import of data and parameters of real elements and materials. This week, we focus on the import of the height profile of a microstructure and of material data into VirtualLab Fusion.

Cross-Platform Optical Modeling and Design with VirtualLab Fusion and Ansys optiSLang

[March 09, 2021]
The optimization of a modern optical system often involves a large number of parameters. This leads to a challenging and numerically demanding task. With the optiSLang Bridge you can directly access the downhill simplex and especially the evolutionary algorithm from optiSLang without leaving VirtualLab Fusion, and the optimization results are also automatically returned in the VirtualLab Fusion session.

The optimization of a modern optical system often involves a large number of parameters. This leads to a challenging and numerically demanding task. For such cases, in addition to the Parametric Optimization feature provided by VirtualLab Fusion, we also offer an interface to the specialized optimization software ANSYS optiSLang, so that several of its advanced optimization algorithms can be applied directly on your optical system. With the optiSLang Bridge (requires a separate license for optiSLang) you can directly access the downhill simplex and especially the evolutionary algorithm from optiSLang without leaving VirtualLab Fusion, and the optimization results are also automatically returned in the VirtualLab Fusion session.

Real vs. Ideal Beam Splitters in a Mach-Zehnder with VirtualLab Fusion

[March 03, 2021]
The Mach-Zehnder interferometer soon became one of the most popular interferometric setups and is still today applied for certain applications. VirtualLab Fusion enables the detailed modeling of the system, including the two 90° phase shifts caused by the real beam splitters.
[March 03, 2021]

The Mach-Zehnder interferometer, invented in the early 1890s, soon became one of the most popular interferometric setups and is still today applied for certain applications. Due to its characteristic well-separated light paths, which are traversed only once, it is a highly configurable instrument (in contrast to e.g. the Michelson interferometer). Two 50:50 beam splitters are used to split a collimated beam into two parts and to subsequently superimpose them back together at the exit. VirtualLab Fusion enables the detailed modeling of the system, including the two 90° phase shifts caused by the real beam splitters.

Customization in VirtualLab Fusion

[February 26, 2021]
This weeks’ newsletter is dedicated to customization via programming. One easy way to configure a customized object is by programming a snippet. Snippets are programmable templates which specify a clear framework for users to generate their objective quickly. For an in-depth understanding of how snippets work, please check out our use cases.
[February 26, 2021]

In VirtualLab Fusion any optical entity is treated as an object. These objects have specific characteristics and may be saved and re-used independently. Among the most known of these objects are the sources, components and detectors. VirtualLab Fusion comes equipped by default with an extensive list of predefined optical objects like a Gaussian source. Despite the versatility of all these "off-the-shelf" components, there are situations in which maybe a specific part of a specialized optical setup cannot be covered with the available predefined objects. The good news is users may tackle this challenge with the help of customization in VirtualLab Fusion.
