Abstract: We demonstrate a 2D beam-steering device in SiN based on a large focusing grating, achieving a steering range of 3.2∘ ×46∘ , with discrete steps in azimuth. Despite the curved geometry, it ...

Pre-training by numerous image data has become defacto for robust 2D representations. In contrast, due to the expensive data processing, a paucity of 3D datasets severely hinders the learning for high ...
