Anisotropic metamaterials for scalable photonic integrated circuits: a review on subwavelength gratings for high‐density integration

open access: yesNanophotonics, Volume 14, Issue 9, Page 1311-1331, April 2025.
Abstract Photonic integrated circuits (PICs) are transforming optical technology by miniaturizing complex photonic elements and systems onto single chips. However, scaling PICs to higher densities is constrained by optical crosstalk and device separation requirements, limiting both performance and size. Recent advancements in anisotropic metamaterials,
