论文摘要
理论上研究了等离子核壳纳米球附近的两个点偶极发射器的集体自发发射。基于模式函数在矢量球形谐波中的扩展,我们为合作衰减速率和偶极 - 偶极相互作用强度都得出了封闭的分析表达式,与靠近球体的两个点偶极子相关。考虑到芯内包含线性扩增培养基的等离激元纳米壳,两个发射器的二阶相关函数表明,可以调整光子发射,选择光子束或抗抗激素作为偏振和球体位置的函数。该结果为涉及工程人工媒体中的可调节单光源来源的应用打开了远景。
The collective spontaneous emission of two point-dipole emitters near a plasmonic core-shell nanosphere is theoretically investigated. Based on the expansion of mode functions in vector spherical harmonics, we derive closed analytical expressions for both the cooperative decay rate and the dipole-dipole interaction strength associated with two point dipoles close to a sphere. Considering a plasmonic nanoshell containing a linearly amplifying medium inside the core, the second-order correlation function for the two emitters shows that it is possible to tune the photon emission, selecting either photon bunching or antibunching as a function of the polarization and position of the sphere. This result opens vistas to applications involving tunable single-photon sources in engineered artificial media.
