Slanted Gratings

We show, in accordance to existing examples from literature, how to model slanted gratings with different geometries with the Fourier modal method (FMM) in VirtualLab Fusion.

Slanted gratings have been found to be of advantage in lightguide-based display systems for AR/MR applications. Such gratings often have periods that are comparable to the wavelength. Therefore, rigorous computational methods must be used to evaluate their performance. We show, in accordance with existing examples from literature, how to model slanted gratings with different geometries using the Fourier modal method (FMM) in VirtualLab Fusion. Additionally, customized slanted gratings can be designed with the help of parametric optimization.

Large-Angle Dot Projector

[September 17, 2019]

In VirtualLab Fusion, by connecting different field solvers, we demonstrate how a dot project works.

A large-angle dot projector is the key optical component in Apple’s Face ID, which casts a structured dot pattern onto the face so as to create a 3D facial map. The dot projection system often employs an array of VCSEL units. Light from the VCSEL array is first collimated by a lens system, and then replicated by a two-dimensional grating into a large angular range. Simulation of such systems would require an appropriate model of the VCSEL source, a dependable handling of the lens system, and a rigorous method for gratings with relatively small periods. In VirtualLab Fusion, this connection of different field solvers is par for the course; we use this ability below in a demonstration of how a dot projector works.
