摘要

我们优化了基于InAs/AlGaAs量子点的光子纳米天线在红光谱范围内工作的单光子源的几何参数。这使得确定圆柱形纳米天线的横向尺寸范围成为可能，在该范围内，辐射提取到数值孔径NA = 0.42的效率最高。与平面结构相比，优化后的纳米结构的萃取效率有所提高。研究了声子参与光泵浦下单光子相关的统计。零延迟二阶相关函数g(2)(0)的值为0.065。

Single-Photon Source for the Red Spectral Range Based on a Nanoantenna with InAs/AlGaAs Quantum Dots

We optimize the geometric parameters of the single-photon source operated in the red spectral range, which is based on a photonic nanoantenna with InAs/AlGaAs quantum dots. This made it possible to determine the range of the transverse dimensions of the cylindrical nanoantenna, within which the maximum efficiency of radiation extraction into the numerical aperture NA = 0.42 is achieved. An increase in the extraction efficiency as compared to a planar structure was demonstrated for the optimized nanostructure. The statistics of single photon correlations under optical pumping with participation of acoustic phonons is studied. The value of the zero-delay second-order correlation function g⁽²⁾(0) was 0.065.
