在过去的二十年里，硅光子学领域取得了重大进展。硅光子学在许多数据处理和传输应用中提供了实质性的性能优势。到目前为止，有源硅光子学在低温系统中的好处尚未被探索。在这里，我们展示了一个高速，CMOS兼容的硅微盘调制器传输数据的速率高达10 Gb/s和温度低至4.8 K的操作。这为使用硅光子作为低温、带宽密集型系统的接口打开了大门，例如基于超导的高性能计算和与超导单光子探测器接口的集成量子光学电路。
Significant progress has been made in the field of silicon photonics over the past two decades. Silicon photonics provides substantial performance advantages in many data processing and transfer applications. Until now, the benefits of active silicon photonics in cryogenic systems have remained unexplored. Here we demonstrate the operation of a high-speed, CMOS compatible silicon micro-disk modulator transmitting data at rates up to 10 Gb/s and at temperatures down to 4.8 K. This opens the door for the use of silicon photonics as an interface to low temperature, bandwidth intensive systems such as high-performance superconducting-based computing and integrated quantum optics circuits interfacing to superconducting single-photon detectors.
