平面光子纳米结构在量子光学中的应用近年来引起了人们的极大关注。在本文中，我们进行了全三维数值模拟，充分考虑到所有的辐射通道，从而量化的耦合效率嵌入在光子晶体波导的量子发射器。我们确定了从量子发射器到周围环境的泄漏，并研究了其光谱和空间依赖性。耦合效率β因子的空间映射表明，即使对于中等慢的光，也可以实现接近1的β因子，并且对波导中发射器的位置具有显著的鲁棒性。
Planar photonic nanostructures have recently attracted a great deal of attention for quantum optics applications. In this paper, we carry out full 3D numerical simulations to fully account for all radiation channels and thereby quantify the coupling efficiency of a quantum emitter embedded in a photonic-crystal waveguide. We determine the leakage from the quantum emitter to the surrounding environment and study its spectral and spatial dependence. The spatial maps of the coupling efficiency, the β factor, reveal that even for moderately slow light, a near-unity β factor is achievable and is remarkably robust to the position of the emitter in the waveguide.
