Abstract

We analyze the two-photon cooperative emission of excited atoms in microcavities with dimensions of the order of the emission wavelength. Here the two-photon dipole-forbidden transitions between the upper and the ground states of the three-level system are possible through the intermediate level that is off resonance with microcavity modes. In this situation one obtains the powerful pulse of two-photon highly correlated light. The superbunching phenomenon in radiated field is also discussed.

微腔中双光子超辐射的可能性
我们分析了微腔中激发原子的双光子协同发射,其尺寸为发射波长的数量级。通过与微腔模式非共振的中间能级,三能级系统的上基态和基态之间的双光子偶极子禁止跃迁是可能的。在这种情况下,人们得到了双光子高度相关光的强大脉冲。讨论了辐射场中的超聚束现象。
