Stacked metasurfaces for enhancing the emission and extraction rate of single nitrogen-vacancy centers in nanodiamond

Abstract

Dielectric metasurfaces with unique possibilities of manipulating light-matter interaction lead to new insights in exploring spontaneous emission control using single quantum emitters. Here, we study the stacked metasurfaces in one- (1D) and two-dimensions (2D) to enhance the emission rate of a single quantum emitter using the associated optical resonances. The 1D structures with stacked bilayers are investigated to exhibit Tamm plasmon resonance optimized at the zero phonon line (ZPL) of the negative nitrogen-vacancy (NV-) center. The 2D stacked metasurface comprising of two-slots silicon nano-disks is studied for the Kerker condition at ZPL wavelength. The far-field radiation plots for the 1D and 2D stacked metasurfaces show an increased extraction efficiency rate for the NV- center at ZPL wavelength that reciprocates the localized electric field intensity. The modified local density of optical states results in large Purcell enhancement of 3.8 times and 25 times for the single NV- center integrated with 1D and 2D stacked metasurface, respectively. These results have implications in exploring stacked metasurfaces for applications such as single photon generation and CMOS compatible light sources for on-demand chip integration.

Purcell and Collection Efficiency Enhancement of Single NV‐ Center Emission Coupled to an Asymmetric Tamm Structure

“…The $$\Delta \lambda $$ at normal incidence for TPR 1 is 4.6 nm which is relatively less compared to $$\Delta \lambda = 13.8nm$$of conventional Tamm structure at the same TPR wavelength. [ 38 ] Figure 3d shows the variation of the Q ‐factor with the angle of incidence for the asymmetric Tamm structure. The Q ‐factor is estimated to be 140 at normal incidence for TPR 1 , and it increases (decreases) for TE (TM) polarization as the angle of incidence increases seen in Figure 3d.…”

Metasurfaces toward Optical Manipulation Technologies for Quantum Precision Measurement

“…The modification of the local density of optical states enables Purcell enhancements of single NV centers by a factor of 3.8 and 25 for 1D and 2D stacked metasurfaces, respectively. [ 210 ] These findings provide guidance for the potential use of stacked metasurfaces as on‐chip nanophotonic sources and offer new insights into quantum metasurfaces and cavity quantum electrodynamics.
