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
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.
One Physical-Optics Platform – Many Field Solvers!
In this new webinar series we present the mathematical toolkit that helps make fast physical optics a reality, show how this toolkit is directly reflected in the user interface, and illustrate the impact it has for the average user, with an added bonus – a sneak peek into the coming release! In this first instalment we discuss one of our key strategies: connecting different field solvers on a single simulation platform – VirtualLab Fusion.
Analysis and Design of Coupling Systems for Single-Mode Fibers
A sound analysis of the performance of a system whose purpose is to couple light into an optical fiber forcefully passes through a full physical-optics simulation of the setup, as does a successful design of such a system: a small deviation in the position of the fiber entrance or in the beam profile, can affect the resulting coupling efficiency, with unnecessary waste of resources ensuing.
VirtualLab Fusion, as a fully vectorial physical-optics software package, provides:
- a flexible source model to realistically mimic the properties and behavior of light,
- an array of field solvers capable of efficiently simulating light propagating through high-NA lenses,
- a fast propagation operator to calculate the field in the focal region,
- and a bespoke detector for calculating the coupling efficiency via the overlap integral with respect to a fully customizable reference mode.
In this webinar we will take advantage of all the above to guide the users through the following workflow, specific to the analysis and design of fiber-coupling systems:
Non Sequential Physical Optics
From the version 7.3 of VirtualLab Fusion, one most important feature is the non-sequential modeling of electromagnetic field propagation through optical systems. This feature is vitally crucial for accurate modeling of an optical system, e.g., interferometers, etalon, as well as visual effects, e.g., ghost image caused by multi-reflection between optical interfaces. This webinar shows the feature concept, as well as how to enable it in VirtualLab Fusion.
