标题： Scanning emitter lifetime imaging microscopy for spontaneous emission control

摘要： 我们报告了一种实验技术，用于映射和利用任意平面纳米光子结构的局部态密度。 该方法依赖于将一个自发发射器相对于其光子环境以确定性和可逆的方式定位在扫描探针上，同时测量其寿命。 我们通过成像金属纳米线周围局部态密度的增强来演示该方法。 通过纳米定位，点光源的衰减率可以通过耦合到导波等离激元模式而被可逆且反复地改变两倍。 显示英文摘要

摘要： We report an experimental technique to map and exploit the local density of optical states of arbitrary planar nano-photonic structures. The method relies on positioning a spontaneous emitter attached to a scanning probe deterministically and reversibly with respect to its photonic environment while measuring its lifetime. We demonstrate the method by imaging the enhancement of the local density of optical states around metal nanowires. By nano-positioning, the decay rate of a pointlike source of fluorescence can be reversibly and repeatedly changed by a factor of two by coupling it to the guided plasmonic mode of the wire.
