摘要

我们介绍并研究了一种嵌入椭圆固体浸透透镜（e-SIL）的高指向性金刚石光学纳米结构。我们深入分析了远场演变与几何修饰之间的关系。这种设计能够在优化位置产生约 11 dB 的最大指向性。在偶极子变化的大范围内，对几何容差和指向性进行了研究。考虑到实验模拟环境，入射光源噪声通过对 e-SIL 几何形状的处理得到了中和。增强 NV 中心零声子线 (ZPL) 区域附近的指向性并降低激发光源噪声，可提高 NV 单光子发射器的整体效率，并可用于多种光子应用。

A geometry dependent directivity analysis of an optical structure based on NV center in diamond

We present and investigate a highly directional diamond based optical nanostructure embedded with an elliptical solid immersion lens (e-SIL). An in depth analysis of the far field evolution is elucidated with respect to geometrical modification. This design is capable of producing a maximum directivity of ~11 dB at its optimized position. Geometrical tolerance and directional behavior has been studied within a wide range of dipole variation. The incident light source noise is neutralized with the manipulation of e-SIL geometry by considering an experimental simulation environment. Enhancement in directivity near NV center zero phonon line (ZPL) region with reduced excitation light source noise can improve the overall efficiency of the NV single photon emitter and can be useful for multiple photonic applications.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
