光子晶体是20世纪80年代末提出的新概念和新材料,光子晶体中存在着光子能隙,正是由于这种光子能隙的出现,产生许多新的物理现象,这种新的物理现象具有重大的理论价值,简单介绍光子晶体的概念和特征,光子晶体的制备方法和理论研究方法,最后简单给出光子晶体的应用。
Photonic crystals are new concepts and new materials proposed in the late 1980s. Photonic energy gaps exist in photonic crystals. It is precisely because of the appearance of such photonic energy gaps that many new physical phenomena are produced. This new physical phenomenon has A great theoretical value, a brief introduction to the concept and characteristics of photonic crystals, the preparation of photonic crystals and theoretical research methods, and finally gives the application of photonic crystals.
