We describe experiments and theory showing the generation of counterpropagating paired photons with coherence times of about 50 ns and waveforms that are controllable at a rudimentary level. Using cw lasers, electromagnetically induced transparency and cold 87Rb atoms we generate paired photons into opposing single-mode optical fibers at a rate of approximately 12 000 pairs per second.
我们描述了实验和理论，展示了具有约50纳秒相干时间且波形可在基本水平上进行控制的反向传播成对光子的产生。利用连续波激光器、电磁诱导透明以及冷87Rb原子，我们以每秒约12000对的速率将成对光子产生到相对的单模光纤中。
