摘要
人工微结构可以捕获特定频率的电磁波,其为增强光与物质相互作用以及调控光场的重要平台之一。连续体束缚态在能谱上位于辐射连续区域,其是开放波动系统中与辐射连续态完全正交的本征态。连续体束缚态源于波动的相干相消,可以极大地抑制微纳光子器件的辐射损耗,为解决人工微纳结构中的光束缚提供全新思路。本文回顾连续体束缚态的发展历程,着重阐述连续体束缚态的理论模型在不同人工光学微纳结构中的进展与应用。连续体束缚态有望促进光通信、集成光学及高效率光场调控等领域的发展。
Abstract
Artificial microstructure, due to its ability to trap electromagnetic waves of a specific frequency, which is one of the important platforms to enhance light-matter interactions and manipulate optical fields. Bound states in the continuum (BICs) are located in the continuous radiation region in the spectra, which are an eigenstate completely orthogonal to the radiation continuum in an open wave system. Originating from the destructive interference of waves, BICs can greatly suppress the radiation loss of micro-nano photonic devices, which offer a brand-new solution to optical binding in artificial micro-nanostructures. In this paper, the historical developments of BICs are briefly reviewed. Besides, the advancements and applications of the theoretical models of BICs in different optical artificial micro-nanostructures are emphatically introduced. In conclusion, BICs are expected to boost further progress in optical communications, integrated photonics, and efficient optical field manipulation.
