Abstract
Bound states in the continuum (BICs) refer to nonradiative eigenmodes located within the radiation continuum, possessing infinitely high Q-factor and enabling exceptionally strong light–matter interactions. BICs have found applications across various domains in photonics and metasurfaces, including nonlinear optical enhancement, vortex beam generation, sensor technology, microlasers, and other related areas. This work starts by classifying the phenomena of BICs and introducing the theoretical formation mechanisms and topological characteristics. Then, the current and advanced applications based on BIC-devices are highlighted. Lastly, this work discusses the current challenges in studies related to BICs, such as structural precision, material selection, and measurement difficulties, and prospect the possible potentials in future developments. This review provides a theoretical background and application prospects of BIC-engineered devices in optical and photonics fields, laying a solid foundation for future industrial applications.
期刊介绍:
Annalen der Physik (AdP) is one of the world''s most renowned physics journals with an over 225 years'' tradition of excellence. Based on the fame of seminal papers by Einstein, Planck and many others, the journal is now tuned towards today''s most exciting findings including the annual Nobel Lectures. AdP comprises all areas of physics, with particular emphasis on important, significant and highly relevant results. Topics range from fundamental research to forefront applications including dynamic and interdisciplinary fields. The journal covers theory, simulation and experiment, e.g., but not exclusively, in condensed matter, quantum physics, photonics, materials physics, high energy, gravitation and astrophysics. It welcomes Rapid Research Letters, Original Papers, Review and Feature Articles.
