摘要:

我们提出了一种机制,以产生不可区分的单光子脉冲的需求,从光学腔。在四能级原子的两个拉曼跃迁处,两个激光脉冲的序列产生相同的腔模光子,而在光子产生之间没有原子的再泵浦。光子从腔中发射,具有近单位的效率,在由激光场控制的相同形状的明确定义的时间模式。二阶关联函数揭示了该光源的单光子性质。一个现实的实验实现的设置。

英文摘要:

We present a mechanism to produce indistinguishable single-photon pulses on demand from an optical cavity. The sequences of two laser pulses generate, at the two Raman transitions of a four-level atom, the same cavity-mode photons without repumping of the atom between photon generations. Photons are emitted from the cavity with near-unit efficiency in well-defined temporal modes of identical shapes controlled by the laser fields. The second order correlation function reveals the single-photon nature of the proposed source. A realistic setup for the experimental implementation is presented.
