Abstract

The spectral characteristics of a microdisk in a diamond substrate with metal gates are simulated. It is shown that the radiative quality factor of a microdisk depends on the parameters of the substrate and the gates. Q-factor oscillations are detected with increasing distance between the disk and the substrate. The spectroscopic response of a microdisk with an NV center is obtained, and the effect of the substrate and the gates on the signal-to-noise (S/N) ratio of this system is studied. It is shown that this ratio can be significantly increased by selecting the structure’s parameters so that the radiative Q factor is maximum.

金刚石基底中的单光子响应和微盘光谱

摘要

模拟了具有金属门的金刚石基板中微盘的光谱特性。结果表明，微盘的辐射品质因数取决于衬底和栅极的参数。随着磁盘和基板之间距离的增加，可以检测到Q因子振荡。获得了具有NV中心的微盘的光谱响应，并研究了衬底和栅极对该系统信噪比（S / N）的影响。结果表明，通过选择结构参数可以显着提高该比率，从而使辐射Q因子最大。
