论文摘要

对完美的单光子源的追求包括找到令人兴奋的量子发射极的最佳协议。基于最近提出的所谓的超级(量子发射极种群的摇摆),我们在实验上证明了两个红色消失的激光脉冲,这两个脉冲都无法单独产生显着的上层群体,从而导致半导体量子点的相干激发。我们表征发射的单光子,并表明它们具有与共振激发方案下实现的属性相当的性能。

The quest for the perfect single-photon source includes finding the optimal protocol for exciting the quantum emitter. Based on a recently proposed, so-called SUPER (swing-up of quantum emitter population) scheme, we demonstrate experimentally that two red-detuned laser pulses, neither of which could yield a significant upper-level population individually, lead to the coherent excitation of a semiconductor quantum dot. We characterize the emitted single photons and show that they have properties comparable to those achieved under resonant excitation schemes.
