论文摘要
我们创建和隔离单光子发射器，高亮度接近$ 10^5 $计数，每秒在商业硅启动器（SOI）晶圆中。发射发生在红外光谱范围内，在电信O波段中具有光谱狭窄的零声子线，即使在连续运行几天后，也显示出高光稳定性。发射器的起源归因于所谓的G中心硅中与碳相关的颜色中心之一，可以使用$^{12} $ C和$^{28} $ SI同位素进行纯化。此外，我们设想了高度可伸缩的量子光子平台的概念，其中单光子源，波导和检测器集成在SOI芯片上。我们的结果为实施与当今硅技术兼容的量子处理器，中继器和传感器提供了一条途径。
We create and isolate single-photon emitters with a high brightness approaching $10^5$ counts per second in commercial silicon-on-insulator (SOI) wafers. The emission occurs in the infrared spectral range with a spectrally narrow zero phonon line in the telecom O-band and shows a high photostability even after days of continuous operation. The origin of the emitters is attributed to one of the carbon-related color centers in silicon, the so-called G center, allowing purification with the $^{12}$C and $^{28}$Si isotopes. Furthermore, we envision a concept of a highly-coherent scalable quantum photonic platform, where single-photon sources, waveguides and detectors are integrated on a SOI chip. Our results provide a route towards the implementation of quantum processors, repeaters and sensors compatible with the present-day silicon technology.
