New VirtualLab Fusion 2023.2!

We are proud to announce the release of the latest version of the optical modeling and design software VirtualLab Fusion, 2023.2!

The signature technology of VirtualLab Fusion is its interoperability of modeling techniques on a single software platform, which allows you to have full control of the balance between accuracy and speed that is always an unavoidable aspect of simulation technology. Version 2023.2 expands on this concept, pursuing the development goals we have set ourselves to offer ever higher speed, easier use, more physics, deeper transparency, and more control.

In this webinar we will be giving a rundown of the most prominent features of this latest version, chief among them:

• The Distributed Computing Package: the perfect tool to tremendously increase simulation speed in complex tasks composed of a large set of individual elementary simulations, and
• The Parameter Variation Analyzer: which enables the detailed analysis of multiplexed systems by flexible evaluation of parameter sweeps and definition of customized merit functions.

There are of course many other novelties to look forward to in VirtualLab Fusion 2023.2!

Optical Design of AR/MR Devices

13 June 2023
10:00 – 11:00 or 18:00 – 19:00 (CEST)
Free Webinar
 

The design of optical devices for augmented and mixed reality (AR & MR) epitomizes the most important challenges that one must unavoidably face in the modeling and design process of complex optical systems for modern applications: striking a delicate balance between accuracy and speed, while retaining the flexibility as a user to adjust said balance as necessary.

Complex physical effects like the interference between overlapping beam footprints and how it affects eye-box uniformity, the coherence properties of the employed source, the entanglement between the initial polarization state of the light that enters the system and the vectorial effects introduced by the different components in the system, or the influence of diffraction on the point spread function/modulation transfer function of the device up to and including the human eye, are just a handful of examples of complex physical phenomena which couple together in an AR/MR waveguide to influence the final performance of the device.

Being able to include all these effects (and many more!) when required, while at the same time ensuring that the simulation remains as fast as possible, is exactly what the software VirtualLab Fusion offers through its flexible combination of interoperable modeling techniques on a single platform. And you always remain in the driving seat, with full control of the simulation parameters, so that you can strike the balance that you need.

Join our webinar to not only see what VirtualLab Fusion is already capable of in the field of AR & MR, but also to get a sneak peek at the exciting upcoming features, like the Distributed Computing Toolbox and the Optimization Toolbox!

You will afterwards surely agree with us when we say:

"VirtualLab Fusion. As accurate as needed. As fast as possible."

Fast Physical Optics in Systems with Diffraction Gratings and DOEs

21 March 2023
10:00 – 11:00 or 18:00 – 19:00 (CET)*

Diffraction gratings are an integral part of many modern optical applications and systems. It is not uncommon for gratings to be just one part of a more complex optical system, which often can contain lenses and other types of optical components.

This combination can be challenging from a simulation perspective: diffraction gratings, particularly those with smaller feature sizes, necessitate a rigorous method to solve Maxwell’s equations – a particularly well-suited choice being the Fourier Modal Method/Rigorous Coupled Wave Analysis (FMM/RCWA), since it is a solver that rests on the assumption of periodicity in the problem. However, these methods are nothing short of overkill when it comes to dealing with lenses and other macroscopic elements: the stringent sampling requirements of the FMM make it impracticable to simulate a typical, macroscopic lens with this algorithm.

This type of complex system is one of the strongest suits of the fast physical optics modeling and design software VirtualLab Fusion: its non-sequential “connecting field solvers” technology makes it possible to use the FMM for the gratings in your system, another solver for propagation in free space, and a different one for the lenses, each solver resting on assumptions that make sense for the component where it is applied. The consistent use of the electromagnetic model for the light means that complex vectorial behavior (e.g., polarization effects from the grating combined with a strong longitudinal component in strongly focused light) are taken into account in the simulation.

We have selected the following examples for this webinar:

• Optical System for Inspection of Micro-Structured Wafer
• Design and Rigorous Analysis of Non-Paraxial Diffractive Beam Splitter

VirtualLab Fusion 2023: The Detector Revolution

Speakers: Prof. Frank Wyrowski and Christian Hellmann

The physical optics software VirtualLab Fusion propagates electromagnetic fields through the optical system to the detectors. The fields provide all information about light. Thus, detectors can evaluate any detector function, e.g., aberrations, amplitude, intensity, irradiance, illuminance, radiant and luminous intensity, degree of coherence, polarization, color temperature, beam parameters, spot size, and the shape and length of an ultrashort pulse. VirtualLab Fusion 2023.1 maximizes the benefit of this fact by introducing the universal detector. It obtains the electromagnetic field and from that detector add-ons calculate any type of detector signal. We steadily provide more detector add-ons independently of the release dates. The webinar introduces you to this amazing new detector concept and gives practical modeling demonstrations.

Theory and Practice: Seamless Transition between Physical and Geometrical Optics Modeling

Speakers: Prof. Frank Wyrowski and Christian Hellmann

We are convinced, that a modern optics software must be based on physical optics. Hence, VirtualLab Fusion is a physical optics software. The use of physical optics is only practical, if the modeling software applies fast algorithms, i.e., algorithms with a complexity linear in the number of sampling points, wherever possible. That is what we do and thus VirtualLab Fusion is a fast physical optics software. Physical optics includes geometrical optics. VirtualLab Fusion embodies this fact by applying a unique concept to provide geometrical optics modeling within the framework of physical optics. It enables a seamless transition between geometrical and physical optics modeling in practice. VirtualLab Fusion 2023.1 takes this amazing technology to the next level.

The webinar gives theoretical insights combined with practical modeling demonstrations.
