Collective near‐field effects in perspective 2D materials containing semiconductor quantum emitters can be used to design novel devices for light manipulation on the nanoscale. The present paper considers an energy conversion from the pump laser field to the surface plasmon polaritons (SPPs) on the base of the hybrid optoplasmonic multi‐level scheme of near‐resonant interaction with semiconductor quantum dots (QDs) placed in the proximity of a graphene surface. Using numerical simulations and semiclassical approach for the light–matter interaction, it is shown that maximum efficiency of SPP generation is achieved in strong coupling conditions for a stationary regime of SPP‐QD interaction. Besides, the conditions for observation of SPP collective resonances in an ordered array of optically excited QDs placed above graphene are determined. Finally, the use of the constructive SPP interference regime in a meta‐layer of QDs above graphene for efficient near‐field amplification and subwavelength light concentration is proposed and discussed.

在石墨烯附近的量子点阵列中激发具有表面等离激元极化的集体共振的混合方案。

包含半导体量子发射器的2D透视材料中的集体近场效应可用于设计用于纳米级光控制的新颖设备。本文考虑了在与石墨烯附近的半导体量子点(QD)发生近共振相互作用的混合光子等离子体多能级方案的基础上,将能量从泵浦激光场转换为表面等离振子极化子(SPP)。表面。使用数值模拟和半经典方法进行光-质相互作用,结果表明,在强耦合条件下,对于SPP-QD相互作用的平稳状态,SPP生成的效率最高。此外,确定观察置于石墨烯上方的光激发QD的有序阵列中的SPP集体共振的观察条件。最后,
