| 中文摘要 | Using the response formula of photonic crystals and Bloch equations, we analyzed the coherent emission in a two-level atom embedded in an arbitrary photonic crystal. We derived a formula for the transient emission expressed by the photon density of states (DOS), the Rabi frequency, and the background decay. Near the band edge, when the ratio of the Rabi frequency to the decay rate is a proper value, a transient gain occurs and the sharp structures of the DOS near the band edge lead to a drastic enhancement of the emission and the oscillation of the emission. |
