Abstract

Continuous development of photonic crystals (PCs) over the last 30 years has carved out many new scientific frontiers. However, creating tunable PCs that enable flexible control of geometric configurations remains a challenge. Here we present a scheme to produce a tunable plasma photonic crystal (PPC) 'kaleidoscope' with rich diversity of structural configurations in dielectric barrier discharge. Multi-freedom control of the PPCs, including the symmetry, dielectric constant, crystal orientation, lattice constant, topological state, and structures of scattering elements, has been realized. Four types of lattice reconfigurations are demonstrated, including transitions from periodic to periodic, disordered to ordered, non-topological to topological, and striped to honeycomb Moiré lattices. Furthermore, alterations in photonic band structures corresponding to the reconstruction of various PPCs have been investigated. Our system presents a promising platform for generating a PPC 'kaleidoscope', offering benefits such as reduced equipment requirements, low cost, rapid response, and enhanced flexibility. This development opens up new opportunities for both fundamental and applied research.

可灵活控制拓扑结构和电磁的等离子光子晶体 "万花筒"。
过去 30 年来,光子晶体(PC)的不断发展开拓了许多新的科学前沿。然而,要制造出能灵活控制几何构型的可调谐光子晶体仍是一项挑战。在这里,我们介绍了一种在介质阻挡放电中制造可调谐等离子体光子晶体(PPC)"万花筒 "的方案,它具有丰富多样的结构配置。我们实现了对等离子光子晶体的多自由度控制,包括对称性、介电常数、晶体取向、晶格常数、拓扑状态和散射元件的结构。演示了四种类型的晶格重构,包括从周期到周期、无序到有序、非拓扑到拓扑以及从条纹到蜂巢莫伊里晶格的转变。此外,我们还研究了光子带结构的变化,这些变化与各种 PPC 的重构相对应。我们的系统为生成 PPC "万花筒 "提供了一个前景广阔的平台,具有设备要求低、成本低、响应快和灵活性强等优点。这一发展为基础研究和应用研究开辟了新的机遇。
