标题： Coupling a single solid state quantum emitter to an array of resonant plasmonic antennas

摘要： 等离子共振阵列或超表面能够塑造入射光场和发射过程的局部态密度。 它们比单个纳米天线提供了更大范围的增强发射区域，并具有更高的设计灵活性。 这使得它们在工程光学吸收和发射方面具有重要意义。 在这里，我们研究了一个单量子发射器，即自组装半导体量子点，与等离子超表面的耦合。 我们探讨了纳米天线的光谱特性以及发射器在结构单元中的位置对耦合的影响。 我们在远场区域观察到了由于发射器-阵列耦合引起的共振增强，并发现其与发射器与单个天线相互作用有明显不同。 显示英文摘要

摘要： Plasmon resonant arrays or meta-surfaces shape both the incoming optical field and the local density of states for emission processes. They provide large regions of enhanced emission from emitters and greater design flexibility than single nanoantennas. This makes them of great interest for engineering optical absorption and emission. Here we study the coupling of a single quantum emitter, a self-assembled semiconductor quantum dot, to a plasmonic meta-surface. We investigate the influence of the spectral properties of the nanoantennas and the position of the emitter in the unit cell of the structure. We observe a resonant enhancement due to emitter-array coupling in the far-field regime and find a clear difference from the interaction of an emitter with a single antenna.
