光子晶体及其自组装制备

Photonic Crystals and its Self-assembling Preparation

自从理论计算指出金刚石结构具有完全光子带隙以来,三维光子晶体的理论研究和实验制作一直受到高度重视。光子晶体的制备方法总体上可分为两大类:微制作法和自组装法。前者适合于制备微波、远红外及近红外波段的光子晶体,后者制备近红外、可见或更短波段的光子晶体具有独特的优势。简述了光子晶体的概念和基本特征,并对三维光子晶体的自组装制备方法进行了综述。

Since the theoretical calculations pointed out that the diamond structure possesses complete photonic band gap, significant attention has been paid to the theoretical research and the experimental fabrication of three-dimensional photonic crystals. On the whole, there are two methods for preparation of photonic crystals： microfabrication and self-assembly. The former adapts to preparing photonic crystals in the microwave, far-infrared or near-infrared region, however, the latter has the special advantages of preparing photonic crystals in the near-infrared, visible and even more shorter wavelength region. The concepts and basic characteristics of photonic crystals are presented, and a review of the methods for self-assembly preparation of three-dimensional photonic crystals is given
