光子源是任何量子光子技术的基本组件。利用体晶体通过自发参量下转换产生高计数率和低噪声相关光子对的能力已经成为现代量子光学的基石。然而，未来实用的量子技术将需要可扩展的集成方法，具有高计数率和低噪声特性的波导光子源将是基于芯片的量子技术的重要组成部分。在这里，我们演示了通过硅微环谐振器中自发四波混合产生的光子对，分别报告了最大符合与偶然（CAR）比为602 +/- 37（产生速率为827 kHz），最大光子对产生速率为123 MHz +/- 11 kHz（CAR值为37）。为了克服自由载流子相关的性能退化，我们已经研究了反向偏置的p-i-n结构，证明了对生成速率的提高高达2倍，对CAR的影响可以忽略不计。(C)2013年美国光学学会
Photon sources are fundamental components for any quantum photonic technology. The ability to generate high count-rate and low-noise correlated photon pairs via spontaneous parametric down-conversion using bulk crystals has been the cornerstone of modern quantum optics. However, future practical quantum technologies will require a scalable integration approach, and waveguide-based photon sources with high-count rate and low-noise characteristics will be an essential part of chip-based quantum technologies. Here, we demonstrate photon pair generation through spontaneous four-wave mixing in a silicon micro-ring resonator, reporting separately a maximum coincidence-to-accidental (CAR) ratio of 602 +/- 37 (for a generation rate of 827kHz), and a maximum photon pair generation rate of 123 MHz +/- 11 kHz (with a CAR value of 37). To overcome free-carrier related performance degradations we have investigated reverse biased p-i-n structures, demonstrating an improvement in the pair generation rate by a factor of up to 2 with negligible impact on CAR.
