Grating Optimization for Desired FOV

[March 11, 2019]
In VirtualLab Fusion, the performance of slanted gratings can be rigorously analyzed with the Fourier modal method (FMM, also known as RCWA). And, in combination with the evolutionary algorithm from optiSLang, we show how to optimize the parameters of a slanted grating structure for user-specified targets.

Slanted gratings play an important role in modern waveguide-based near-eye display devices for AR/MR applications. In VirtualLab Fusion, the performance of slanted gratings can be rigorously analyzed with the Fourier modal method (FMM, also known as RCWA). And, in combination with the evolutionary algorithm from optiSLang, we show how to optimize the parameters of a slanted grating structure for user-specified targets, e.g. good uniformity over the desired FOV or high coupling efficiencies on average.

Grating Optimization over Desired FOV

[February 27, 2019]

Using the rigorous Fourier modal method (FMM, also known as RCWA) in VirtualLab Fusion, and the evolutionary algorithm from optiSLang, an optimized grating structure that delivers good uniformity over the desired FOV can be obtained.

Diffractive gratings are often used to couple light into lightguides, and that forms the basis of the near-eye display devices for AR/MR applications. For vision purposes, the diffraction efficiency of the coupling grating must be optimized over a certain field of view (FOV). That is a challenging task. Using the rigorous Fourier modal method (FMM, also known as RCWA) in VirtualLab Fusion, and the evolutionary algorithm from optiSLang, an optimized grating structure that delivers good uniformity over the desired FOV can be obtained.

Gratings are often used for coupling light out of or into lightguides. How to optimize the coupling efficiency is always an important issue in such cases. The coupling gratings usually have feature sizes comparable with the wavelength and therefore require a rigorous modeling technique. VirtualLab Fusion provides convenient tools for the configuration of the grating structures, the rigorous Fourier modal method (FMM) for grating analysis, and also the parametric optimization method. With the combination of these technologies, a practical workflow for coupling grating optimization is presented.

Real digital – How LightTrans masters challenges of AR

[January 30, 2019]
[January 30, 2019]

A few weeks ago LightTrans had the pleasure of being interviewed by SCHOTT. The technology magazine focused this time on the theme "Real digital"; LightTrans seems therefore a very fitting interviewee choice – not only because of our software, but also because of a long-lasting collaboration and the physical proximity between the two companies.

Analysis of Lightguide Coupling

In VirtualLab Fusion, the coupling efficiency can be rigorously calculated with the Fourier modal method (FMM). As an example, we analyzed several selected slanted gratings, and the simulation results show good agreement with those from literature.

Lightguide structures play a role in various applications nowadays, from integrated optics to modern display technology. Coupling light out of or into the lightguide is therefore an issue of concern for all lightguide-based applications. Such tasks are usually realized with diffractive gratings, since they can be integrated with the lightguide using modern fabrication techniques. In VirtualLab Fusion, the coupling efficiency can be rigorously calculated with the Fourier modal method (FMM). As an example, we analyzed several selected slanted gratings, and the simulation results show good agreement with those from literature.
