摘要：

The spontaneous emission rate of a two-level system quantum dots is not intrinsic properties of the emitter itself but is molded by the electromagnetic environment that surrounds it. Photonic crystal micro cavity can conveniently shape the states of electromagnetic modes by providing modes with the required small volumes and high quality factors. This paper studies spontaneous emission from quantum dots embedded in photonic crystal micro cavity, and introduces the coupling characters of photonic crystal and quantum dot, and analyses the effectiveness of spontaneous emission enhancement from quantum dots embedded in photonic crystal micro cavity in detail. The research of this paper provides a basic reference for dynamic control of optics quantum systems.
