Advances in the Construction of Photonic Structures with Dual Stopbands and Beyond

Abstract

Photonic structures find wide applications in a variety of fields. Self-assembly of the building blocks, including block copolymers, homopolymers, liquid crystal and colloidal particles have been the most widely used to construct photonic structures due to their low-cost and widely accessiblity to most ordinary laboratories. In recent years, the emerging photonic structures with more than a single stopband has attracted considerable attention due to the demand for the integration of different photonic structures for biomimetics and miniaturized devices, despite vast majority of research has focused on single stopband photonic structures. However, a review that systematically covers the progress in the development of photonic structures with multiple stopbands is yet to be summerized. In light of this, we present this review regarding the advances of photonic structures with more than single stopband. We roll out our discussions from two aspects: multiple stopbands bulk photonic structures and microobjects. We expect this review will help researchers to develop new photonic structure with multiple stopbands and address the challenges in design new functional materials to meet the demands for anticounterfeiting, camouflage etc.
