Microring resonators made from silicon are becoming a popular microscale device format for generating photon pairs at telecommunications wavelengths at room temperature. In compact devices with a footprint less than 5 × 10(-4) mm2, we demonstrate pair generation using only a few microwatts of average pump power. We discuss the role played by important parameters such as the loss, group-velocity dispersion and the ring-waveguide coupling coefficient in finding the optimum operating point for silicon microring pair generation. Silicon photonics can be fabricated using deep ultraviolet lithography wafer-scale fabrication processes, which is scalable and cost-effective. Such small devices and low pump power requirements, and the side-coupled waveguide geometry which uses an integrated waveguide, could be beneficial for future scaled-up architectures where many pair-generation devices are required on the same chip.
由硅制成的微环谐振器正成为一种流行的微型器件形式，用于在室温下产生电信波长的光子对。在占地面积小于5×10⁻⁴平方毫米的紧凑型器件中，我们展示了仅使用几微瓦的平均泵浦功率就能产生光子对。我们讨论了诸如损耗、群速度色散和环形波导耦合系数等重要参数在寻找硅微环光子对产生的最佳工作点时所起的作用。硅光子学可以使用深紫外光刻晶圆级制造工艺来制造，这种工艺具有可扩展性且成本效益高。如此小的器件和低泵浦功率要求，以及使用集成波导的侧向耦合波导几何结构，对于未来在同一芯片上需要许多光子对产生器件的放大架构可能是有益的。
