| 摘 要： | 准晶是具有长程有序但不具有周期性的奇特结构。光子准晶以其优越的调控电磁波的能力和广阔的应用前景受到国内外学者的广泛关注。光子准晶不仅具有全带隙、局域态、负折射、近零折射率等一般特性,还因其独特的旋转对称性在激光和非线性频率转换等方面具有优势。本文简要回顾近年来光子准晶的发展历程,从理论研究与应用研究两方面介绍光子准晶研究的主要方向,并对其未来发展趋势进行了展望。

| Abstract: | Quasicrystals have unique structures with long-range order without periodicity. Photonic quasicrystals have been widely studied because of their excellent ability to control electromagnetic waves and broad application prospects. Photonic quasicrystals not only have general characteristics such as complete bandgap, localization states, negative refraction and near-zero refractive index, but also have advantages in laser and nonlinear frequency conversion due to their unique rotational symmetry. In this paper, the development of photonic quasicrystals in recent years is briefly reviewed, and the main research directions of photonic quasicrystals are introduced from two aspects, theoretical researches, and application ones. At last, the future development trend of photonic quasicrystals is prospected. |
