METAGRATINGS FOR LARGE-ANGLE BEAM SPLITTING
Time: 2020-10-09 16:09Source: δ֪Writer: infocrops
Dot-projection optical elements can be found in an ever-growing number of devices, like in the LiDAR of Apple’s new iPad Pro with depth-detecting capability. A beam-splitting grating plays a crucial role in these applications, and the design of such gratings for non-paraxial cases is challenging. Metagratings, because of the unique way in which a nanopillar manipulates the electromagnetic field, can provide additional design possibilities. We demonstrate how such gratings can be constructed, modeled, and optimized in VirtualLab Fusion.

Design of 2D Non-Paraxial Beam-Splitting Metagrating

 
We design a 2D metagrating for beam splitting. The metagrating is constructed, analyzed, and further optimized in VirtualLab Fusion, especially in terms of the uniformity of the diffraction efficiencies.
Metagrating Construction – Discussion at Examples

 
Based on selected examples, we show how to construct and configure metagrating structures and materials in VirtualLab Fusion.
