Abstract
We present the design and experimental demonstration of a micropillar metamorphic cavity structure with an embedded InAs/InGaAs quantum dot, intended for single-photon generation in the telecommunication C‑band. The microcavity, incorporating a single GaAs/AlGaAs distributed Bragg reflector, is designed to provide a photon extraction efficiency of 15% into a numerical aperture of 0.7. The structure, fabricated by molecular beam epitaxy, photolithography, and plasma-enhanced chemical etching, exhibited an average C‑band photon emission rate of \( \sim \)1 MHz at the first lens with a second-order correlation function of \({{g}^{{(2)}}}(0)\) = 0.14.
我们提出了一种嵌入InAs/InGaAs量子点的微柱变质腔结构的设计和实验演示,用于电信C波段的单光子产生。该微腔采用单个GaAs/AlGaAs分布式Bragg反射器,其光子提取效率为15%% into a numerical aperture of 0.7. The structure, fabricated by molecular beam epitaxy, photolithography, and plasma-enhanced chemical etching, exhibited an average C‑band photon emission rate of \( \sim \)1 MHz at the first lens with a second-order correlation function of \({{g}^{{(2)}}}(0)\) = 0.14.
