Topology-optimized freeform broadband optical metagrating for high-efficiency large-angle deflection

Yuting Xiao,
Mingfeng Xu,
Mingbo Pu
et al.

Abstract: A metagrating made of periodic arrays of subwavelength inclusions has great capability for efficient manipulation of the impinging wavefront at subwavelength scale. However, it suffers from a significant practical issue in that the diffraction efficiency declines rapidly along with the increase of deflection angle, especially for broadband application scenarios. Here, we comprehensively investigated different topology optimization approaches to design the broadband optical metagrating for high-efficiency large… Show more
