半导体量子点结构中EIT方案的比较:多体相互作用的影响

Comparison of EIT schemes in semiconductor quantum dot structures: Impact of many-body interactions

J. Houmark, T. R. Nielsen, J. Mork, A. -P. Jauho

摘要:

我们研究了多体相互作用对通过电磁诱导透明量子点中实现的群速度减慢的影响,使用三种不同的耦合探针方案(分别为梯形,V和λ)。我们发现,对于所有的计划,多体相互作用的慢光特性有重要的影响。在Lambda和V方案的情况下,实现慢光所需的最小耦合功率被多体相互作用显著降低。发现V型方案通常是优选的,这是由于载流子在能量空间中的有利再分布。

英文摘要:

We investigate the impact of many-body interactions on group-velocity slowdown achieved via electromagnetically induced transparency in quantum dots using three different coupling-probe schemes (ladder, V, and Lambda, respectively). We find that for all schemes many-body interactions have an important impact on the slow light properties. In the case of the Lambda and V schemes, the minimum required coupling power to achieve slow light is significantly reduced by many-body interactions. V type schemes are found to be generally preferable due to a favorable redistribution of carriers in energy space.
