摘　　要：对光子晶体的性质和应用,如光局域化或光子晶体波导,甚至于是沿着一个很尖锐的弯曲的光子晶体波导能力,以及光子晶体激光器,进行了讨论。在这一技术领域,有许多基础方面的特点被认为是正确的,但却没有给出严格的证明。这是由于下列两方面的原因,第一是这个新领域发展的非常迅速,第二是由于在光子晶体中分析电磁波是很困难的,除了使用计算机去得到定量结果外,没有别的选择。板型的光子晶体(带有一个周期性空洞系统的高折射率板片),对高集成的光电路器件来说,也许是最佳结构。The characteristics and applications of photonic crystal, such as light localization or the ability to guide light even along a sharp bend, and photonic crystal laser, are discussed. In this technical field, there are some fundamental points that many people take for granted but are not rigorously proved. The reasons are as follows. First, this new field has grown very rapidly. Second, because it is very difficult to analyze electromagnetic waves in photonic crystal, one usually has no other choice than to use computers to derive quantitative results. Planar photonic crystals （high - index slabs with a periodic system of holes, or posts） may be the most feasible structures for highly integrated optical circuits.
