We demonstrate an all-dielectric quantum electrodynamical nanowire-slab system with a single emitter that concentrates the extremely intense light at the scale of 10 × 75 nm(2). The quantum dot exhibits a record high 31-fold spontaneous decay rate enhancement, its optical saturation and blinking are strongly suppressed, and 80% of emission couples into a waveguide mode.
我们展示了一种全介质量子电动力学纳米线-平板系统,其中包含一个单发射器,可将极其强烈的光聚焦在 10×75nm² 的尺度内。该量子点表现出创纪录的 31 倍自发衰减速率增强,其光学饱和和闪烁被强烈抑制,并且 80%的发射耦合到波导模式中。
