AI 中文摘要
金刚石中带负电的氮-空位（$\mathrm{NV}^-$）缺陷可通过激发态到基态的辐射衰变读出用于量子信息处理。金刚石与空气之间较大的折射率失配导致全内反射损耗，从而造成光子提取效率低下。在此，我们通过数值模拟研究光子提取，并报道了由高介电常数介质氧化钇稳定氧化锆（YSZ）构成的加法式固体浸没透镜（SILs），用于表面修饰和增强浅层注入氮-空位色心的光提取。我们展示了使用可扩展的自下而上室温脉冲激光沉积和光刻结构化工艺，饱和强度平均增加63%。通过SILs，实现饱和所需的平均激光强度降低了33%。
英文摘要
The negatively charged nitrogen-vacancy ($\mathrm{NV}^-$) defect in diamond can be used for quantum information processing via the readout of the radiative decay of the excited state into the ground state. The large refractive index mismatch of diamond and air causes low photon extraction efficiency due to total internal reflection losses. Here, we investigate the photon extraction numerically and report additive solid immersion lenses (SILs) consisting of the high-k dielectric yttria-stabilized-zirconia (YSZ) for surface modification and enhanced light extraction of shallow implanted nitrogen-vacancy centers. We demonstrate an average increase of 63% in saturation intensity using a scalable bottum up room temperature pulsed laser deposition and photolithography structurization process. The average necessary laser intensity for saturation is reduced by 33% by the SILs.
