一段时间以来，人们已经认识到，原子的自发辐射不一定是物质与空间之间耦合的固定不变的性质，而是可以通过改变辐射场的性质来控制的。这在固态中也是如此，其中自发辐射在限制半导体激光器、异质结双极晶体管和太阳能电池的性能方面起着基本作用。如果三维周期性电介质结构具有与电子带边重叠的电磁带隙，则可以严格禁止自发辐射。
It has been recognized for some time that the spontaneous emission by atoms is not necessarily a fixed and immutable property of the coupling between matter and space, but that it can be controlled by modification of the properties of the radiation field. This is equally true in the solid state, where spontaneous emission plays a fundamental role in limiting the performance of semiconductor lasers, heterojunction bipolar transistors, and solar cells. If a three-dimensionally periodic dielectric structure has an electromagnetic band gap which overlaps the electronic band edge, then spontaneous emission can be rigorously forbidden.
