小原子样品的单光子定向发射

Directional emission of single photons from small atomic samples

Yevhen Miroshnychenko, Uffe V. Poulsen, Klaus Mølmer

摘要:

我们提供了一个形式主义来描述确定性的单光子发射量身定制的空间和时间的配置文件从一个规则的阵列的多能级原子。我们假设一个单一的集体激发最初共享的所有原子在一个亚稳态的原子状态,这个状态是由一个经典的激光场耦合到一个光学激发态,迅速衰减到基态原子。我们的模型通过光激发态的塞曼流形对光的再吸收和发射来解释不同的场偏振分量。

英文摘要:

We provide a formalism to describe deterministic emission of single photons with tailored spatial and temporal profiles from a regular array of multi-level atoms. We assume that a single collective excitation is initially shared by all the atoms in a metastable atomic state, and that this state is coupled by a classical laser field to an optically excited state which rapidly decays to the ground atomic state. Our model accounts for the different field polarization components via re-absorption and emission of light by the Zeeman manifold of optically excited states.
