Fluorescent nanodiamonds (FNDs) with nitrogen-vacancy centers are pivotal for advancing quantum photonics and imaging through deterministic quantum state manipulation. However, deterministic integration of quantum emitters into photonic devices remains a challenge due to the need for high coupling efficiency and Purcell enhancement. We report a deterministic FND-integrated nanofocusing device achieved by assembling FNDs at a plasmonic waveguide tip through plasmonic-enhanced optical trapping. This technique not only increases the emission rate by 58.6 times compared to isolated FNDs but also preferentially directs radiation into the waveguide at a rate 5.3 times higher than that into free space, achieving an exceptional figure-of-merit of ∼3000 for efficient energy transfer. Our findings represent a significant step toward deterministic integration in quantum imaging and communication, opening new avenues for quantum technology advancements.

使用高效纳米聚焦装置增强氮空位纳米金刚石的等离子捕获和荧光发射
具有氮空位中心的荧光纳米金刚石(FND)对于通过确定性量子态操纵推进量子光子学和成像至关重要。然而,由于需要高耦合效率和珀塞尔增强,将量子发射器确定性集成到光子器件中仍然是一个挑战。我们报告了一种确定性 FND 集成纳米聚焦装置,通过等离子体增强光学捕获在等离子体波导尖端组装 FND 来实现。与隔离 FND 相比,该技术不仅将发射率提高了 58.6 倍,而且优先将辐射以比自由空间高 5.3 倍的速率引导到波导中,实现了约 3000 的卓越品质因数,实现了高效的能量传输。我们的发现代表了量子成像和通信中确定性集成的重要一步,为量子技术进步开辟了新途径。
