论文摘要
集成到量子光电电路中的单光子发射器将实现新的，微型的量子光学设备。在这里，我们研究了嵌入低折射率对比度波导的半导体量子点。我们讨论了一个模型，以计算发射光场与波导的基本传播模式的耦合效率，并优化了波导尺寸参数以提高最大耦合效率。此外，我们表明，对于侧面裁切的波导，purcell-Enhaphement和优化的场曲线的相互作用可以提高耦合效率约两个。
Single-photon emitters integrated into quantum optical circuits will enable new, miniaturized quantum optical devices. Here, we numerically investigate semiconductor quantum dots embedded to low refractive index contrast waveguides. We discuss a model to compute the coupling efficiency of the emitted light field to the fundamental propagation mode of the waveguide, and we optimize the waveguide dimensional parameters for maximum coupling efficiency. Further, we show that for a laterally cropped waveguide the interplay of Purcell-enhancement and optimized field profile can enhance the coupling efficiency by a factor of about two.
