受激辐射机制的研究是光子晶体激光器设计中的一个基本问题。采用全量子理论 分析光子晶体中单个二能级原子的受激辐射。讨论的原子能级间跃迁频率在光子带隙内且接 近带隙边缘。在光子晶体中初态光场影响着系统的行为，激发态粒子数布居出现了有趣的现 象：反束缚、周期振荡和准周期振荡。受激辐射的性质明显与初始态的光场和原子激发态能级 相对光子带隙的位置有关。
The study of stimulated emission mechanism is a basic issue in the design of photonic crystal lasers. Quantum theory is used to analyze the stimulated emission of a single two - level atom in a photonic crystal. The transition frequencies between atomic energy levels discussed are within the photonic bandgap and close to the bandgap edge. In the photonic crystal, the initial state light field affects the behavior of the system. There are some interesting phenomena in the population of excited states: anti-binding, periodic oscillation and quasi-periodic oscillation. The nature of the stimulated emission is clearly related to the initial state of the light field and the position of the atomic excited state relative to the position of the photonic bandgap.
