| Abstract Scope |
Resonant light scattering and field confinement in low-index dielectric structures is challenging. We employ computational techniques to demonstrate the Mie-scattering modes of pillar-and-scaffold structures to enhance the spontaneous emission of an NV−1 color center. We started by analyzing the electric field profile for dielectric vertical pillars in silica and extended our analysis to the scaffold structures. The scaffold edges enhance field confinement by modifying the local electromagnetic environment. We also studied high index materials such as SiC, diamond, and Si and observed field enhancement. To improve the resonance effect, the scaffold structures were coated by thin film of silver (Ag) metal to excite surface plasmon polariton (SPP) waves at boundaries of structure. Additionally, we integrated a nitrogen vacancy (NV−1) center in nanodiamond-based quantum emitter at top of pillar and edges of scaffold to calculate emitter's decay rate. The pillar-scaffold structures show good applications in quantum computing, and bio-medical sensing. |
