AR & MR Devices – How to Model Light Guides in VirtualLab Fusion

In our webinar last December we showed you some of the cool things that are possible in the field of augmented and mixed reality with the Light Guide Toolbox of the fast physical optics modeling and design software VirtualLab Fusion. This time, we return to the topic with a much more hands-on approach. In our coming webinar, we will go over some of the most common workflows when working in this field of application with VirtualLab Fusion, so that you can get an impression of the look and feel of the software.

You can expect to see:

• Introduction into VirtualLab’s Light Guide component and set-up of light guide devices
• How to configure and add grating structures
• Step-by-step modeling and evaluation of the set up device

Exploring VirtualLab Fusion

In this webinar we are going to take a very relaxed approach and simply put some time aside to play around with the physical optics modeling and design software VirtualLab Fusion, to get a taste of what its fast physical optics technology can do!

Flat Optics – about Freeform, Fresnel, Diffractive and Meta Lenses

The steady interest in miniaturizing optical systems ultimately leads to flat optics, which includes any concept to reduce the thickness of components and systems by introducing surfaces with high functionality. In this webinar we invite you to join us on a journey through the concepts, prospects, challenges, and myths of the different versions of flat components, with an emphasis on lenses. 

New Features in VirtualLab Fusion for Fiber Optics

VirtualLab Fusion comes with new features for the modeling and design of systems for fiber optics. Based on linearly polarized (LP) modes and Gaussian-Laguerre solver techniques, we present:

• The fiber source, which emits customer-selected weighted fiber modes,
• The fiber coupling efficiency detectors, which provide the efficiency of the power transferred into multi-mode and single-mode fibers,
• The fiber component, which enables the propagation of electromagnetic fields through fibers.

These new features significantly extend the physical-optics modeling and design capability of VirtualLab Fusion for fiber optics applications. This is demonstrated by examples such as:

• Investigating the aberration effects on the fiber modes in the focal region,
• Analyzing the field propagation through an optical system with fiber components,
• Presenting a complete design workflow of the coupling system of either single-mode or multi-mode fiber, including lens system design and tolerance analysis.

Diffractive Lenses: Concept, Modeling, Design, and Fabrication Data

Smooth, often spherical, surfaces between homogeneous media dominate lens design. The introduction of aspherical and freeform surfaces has added design freedom to obtain compact lens systems with improved quality and new functions. According to the Fresnel equations, surfaces typically do not add a phase variation to the incident light. Diffractive surfaces introduce the freedom to add an extra phase variation onto the incident light. Interest in how to use this extra design freedom best has gained momentum in recent years, aiming at more compact systems and better performance. The nature of the diffractive structure allows for special functionalities like multiple foci, but also leads to some challenges, like a strong wavelength dependency.
