Gratings as a Part of Optical Systems

22 October 2020

The construction of optical systems combining diffraction gratings and lenses and other smooth surfaces is a common occurrence. We have selected three examples to illustrate in the webinar the potential of VirtualLab Fusion in this field.

Gratings as a Part of Optical Systems

The construction of optical systems combining diffraction gratings and lenses and other smooth surfaces is a common occurrence, across many applications like spectroscopy, in microscopy using the grating as a test object, or in AR & MR glasses. This is not reflected in the field of simulation: it is rare, even today, to find software which can convincingly tackle the modeling of such systems. The reason for this is the vast difference in the structural dimensions of the two types of components, which means drastically different algorithms are needed for each of them.

Lightguides for Mixed Reality Glasses: Design Techniques and Challenges

16 February 2022

Augmented and mixed reality (AR & MR) devices constitute one of the most exciting developments in optical engineering in recent times: mainly due to the thrilling new applications they enable, but also, from an optical engineer’s perspective, because of the challenges arising from such systems.

 

The fast physical optics modeling and design software VirtualLab Fusion is perfectly placed to become the simulation tool of choice for optical engineers working in AR and MR. Its consistent vectorial treatment of fields takes complex polarization effects into account, while its “connecting field solvers” technology allows us to combine a rigorous field solver for the grating regions of the lightguide with other, less resource-heavy methods for the free-space propagation and the surfaces of the lightguide, to produce a thorough yet efficient result. Additionally, VirtualLab Fusion offers specific detectors and design algorithms to help the optical designer in his AR & MR design tasks.

Lightguides for Mixed Reality Glasses: Design Techniques and Challenges

The use of lightguides with diffraction gratings has become of great interest in the development of augmented reality and mixed reality glasses. The propagation of light through such lightguides requires simulation techniques beyond ray tracing. It must be possible to include physical-optics effects in a controllable manner to meet the needs in modeling and design. This webinar will introduce you to a suitable physical-optics modeling technology and demonstrate it in the software VirtualLab Fusion.

Simulation of Interferometric Setups with VirtualLab Fusion

30 September 2020

In this webinar we will demonstrate the simulation of a series of interferometric setups in the fast physical optics modeling and design software VirtualLab Fusion.

Simulation of Interferometric Setups with VirtualLab Fusion

Interferometry as a discipline proves useful in a wide range of applications, and interferometric setups can just as easily be found in the laboratories of educational institutions for the demonstration of fundamental physical effects to budding students, as in cutting-edge industrial systems for many different purposes, like surface quality characterization and sensing, among others. And that is not to mention the medical and biological fields, where interferometry forms the basis for multiple non-invasive diagnostic tools.

Modeling and Design of Metagratings

02 September 2020

VirtualLab Fusion provides a seamless workflow for design and analyzing metagratings.

Modeling and Design of Metagratings

Metagratings and more general metasurfaces are shown to be potentially powerful devices for various applications. In comparison to the traditional diffractive gratings, metagratings are known for maintaining a high diffraction efficiency in non-paraxial situations. Polarization-insensitive designs are possible with an appropriate selection of the types of nanopillars as the unit cells for the metagratings.

VirtualLab Fusion 2020.1 Release Webinar

08 July 2020

We are proud to present a new version of VirtualLab Fusion, in which we bring the connecting field solvers technology to the next level. We completely do away with the tendency that exists of only considering diffraction effects at the exit pupil of the system.

VirtualLab Fusion 2020.1 Release Webinar

We are proud to present a new version of VirtualLab Fusion, in which we bring the connecting field solvers technology to the next level. We completely do away with the tendency that exists of only considering diffraction effects at the exit pupil of the system, in the process enabling the analysis of laser systems, cascaded diffraction, vignetting, 4f setups as well as of any combination of gratings, microstructures, diffusers, and diffractive and metalenses with conventional and freeform lenses.
