SUPER Scheme in Action: Experimental Demonstration of Red-detuned Excitation of a Quantum Dot
摘要：
对完美单光子源的追求包括找到激发量子发射器的最佳协议。基于最近提出的SUPER（swing-up of quantum emitter population）方案，我们在实验上证明了两个单独都不能产生显著上能级布居的红失谐激光脉冲导致半导体量子点的相干激发.我们的特点，发射的单光子，并表明它们具有可比的共振激发方案下实现的性能。
英文摘要：
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.
