摘　　要：光学超构材料是一种人工设计的微结构材料,它的出现打破了传统材料设计思维的局域性,为在微纳尺度上人为调控电磁波提供了新的范式,实现了具有超越自然界常规材料的光学性质.尤其是超构材料具有将光和电磁辐射耦合到亚波长尺度的能力,满足了高速发展的现代科学技术对光学元器件的高性能、微型化以及集成化的新要求.因此,基于超构材料的光子芯片带来很多令人鼓舞的应用,如突破衍射极限的完美成像、多功能的集成光学器件等.更有意思的是,超构材料光子芯片还可以用来模拟一些广义相对论的现象,尤其是探索一些尚未被实验证实的与引力相关的现象.本文从不同类型的超构材料芯片出发,简要介绍了在光学超构材料芯片上开展的类比引力的研究,最后对其发展现状、优势与面临的挑战进行了相应的总结与展望.Optical metamaterial is a kind of artificially designed microstructured material.Its occurrence breaks the localization of traditional material design thinking and provides a new paradigm for artificially controlling electromagnetic waves on a micro-nano scale,especially realizes optical properties beyond conventional materials in nature.Furthermore,metamaterial has the ability to couple electromagnetic waves into the subwavelength regime,meeting the high-speed development of modern science and technology,which puts forward new requirements for high performance,miniaturization and integration of optical components.Therefore,optical chips based on metamaterials bring many encouraging applications such as in perfect imaging that breaks through the diffraction limit,multifunctional integrated optics,etc.In addition,metamaterial photonic chips can also simulate some phenomena in general relativity,especially exploring some phenomena that have not been experimentally proven.This review paper briefly introduces the study of analogical gravitation based on different kinds of photonic chips on the basis of metamaterials.In the end,there present the summary and outlook about the current development,advantages and challenges of this field.
