论文摘要
我们证明了在多种空间模式下片上单光子生成的光子积分电路中两个量子点的共振激发。这两个量子点使用一对孤立的$ p $ -i $ - $ n $连接将电动调谐到相同的发射波长,并通过双模式波导激发了共鸣泵激光器。我们证明了在窄线宽量点的连续波激发下,$(79 \ pm2)\%$的两光子量子干扰可见性。我们的工作通过实现如何扩展确定性的单光子源的关键功能来解决量子光子学的出色挑战。
We demonstrate the resonant excitation of two quantum dots in a photonic integrated circuit for on-chip single-photon generation in multiple spatial modes. The two quantum dots are electrically tuned to the same emission wavelength using a pair of isolated $p$-$i$-$n$ junctions and excited by a resonant pump laser via dual-mode waveguides. We demonstrate two-photon quantum interference visibility of $(79\pm2)\%$ under continuous-wave excitation of narrow-linewidth quantum dots. Our work solves an outstanding challenge in quantum photonics by realizing the key enabling functionality of how to scale-up deterministic single-photon sources.
