研究了孔径探头对近红外辐射的近场收集效率。我们使用InAs量子点作为理想的点光源，发射波长范围为1.1 ~ 1.6 μm。我们实验研究了收集效率的波长依赖性，并将结果与模拟实际探针结构的计算模拟进行了比较。所观察到的收集效率的退化是由于金包层锥形波导的截止特性，其在近红外波长接近理想导体。
We examined the near-field collection efficiency of near-infrared radiation for an aperture probe. We used InAs quantum dots as ideal point light sources with emission wavelengths ranging from 1.1 to 1.6 μm. We experimentally investigated the wavelength dependence of the collection efficiency and compared the results with computational simulations that modeled the actual probe structure. The observed degradation in the collection efficiency is attributed to the cutoff characteristics of the gold-clad tapered waveguide, which approaches an ideal conductor at near-infrared wavelengths.
