论文摘要
我们研究了在INP上生长的电信波长INAS量子点的发光动力学（111）A，由液滴外延。将三元合金inalgaas用作屏障材料，导致1.55 $ $ $ M $ M TELECOM C波段的光子发射。发光衰减是根据理论间的过渡强度很好地描述的，而没有非辐射重组的影响。强度自相关函数显示清晰的抗束光子光子统计。结果表明，我们的量子点可用于构建单个光子和量子纠缠光子对的实用来源。
We study the luminescence dynamics of telecom wavelength InAs quantum dots grown on InP(111)A by droplet epitaxy. The use of the ternary alloy InAlGaAs as a barrier material leads to photon emission in the 1.55 $μ$m telecom C-band. The luminescence decay is well described in terms of the theoretical interband transition strength without the impact of nonradiative recombination. The intensity autocorrelation function shows clear anti-bunching photon statistics. The results suggest that our quantum dots are useful for constructing a practical source of single photons and quantum entangled photon pairs.
