Characterization of superconducting microwave photonic devices & systems

光子学和高速电子学的结合已经被确立为一种 以光学或电子形式生成、操纵、传输和检测信息的成功技术。 对实现超灵敏、超低噪声和高速/高频器件以及传感、加工和计量应用的不断追求不断推动研究人员寻找新型光电器件和系统。对这种系统的不断探索最近导致了在光电和微波到太赫兹光子器件中使用超导材料以利用其宏观量子行为的可能性。为了使超导光电子学充分发挥其潜力，必须开发和表征器件和系统。该提案要求购买两个研究工具基础设施;楔形超声波引线键合机，使原始超导设备连接到其余的光子和电子设备和测量系统，以及PNA网络分析仪，以执行高频光电特性。这两个单元集成到我们以前建立的基础设施实验室，集成量子光电实验室（IQOL），提供了我们的低温四探针微波站的全面运行，以测试我们现有的和未来的超导光电器件。超导纳米线单光子光探测器，光混合器，光电混频器和开关是我们设备的重要例子，应用范围从光纤量子密码术到活细胞成像和光谱学。

The combination of photonics and high-speed electronics has been established as a   successful technology to generate, manipulate, transmit and detect information either in optical or electrical forms.  The increasing quest for achieving ultra-sensitive, ultra-low noise and high-speed/high-frequency devices with applications in sensing, processing and metrology is constantly pushing researchers to find novel optoelectronic devices and systems. The continuous exploration of such systems has recently led to the possibility of using superconducting materials in optoelectronic and microwave-to-THz photonic devices to take advantage of their macroscopic quantum behavior. In order for superconducting optoelectronics to attain its full potential, devices and systems must be developed and characterized. This proposal requests the purchase of two research tool infrastructures; Wedge ultrasonic wire bonder to make the raw superconducting devices to connect to the rest of photonic and electronic devices and measurement systems and a PNA network analyzer to perform high-frequency optoelectronic characterization. The integration of these two units to our previously established infrastructure laboratory, Integrated Quantum Optoelectronics Lab (IQOL), provides a full operation of our cryogenic four-probe microwave station to test our existing and future superconducting optoelectronic devices. Superconducting nano-wire single-photon optical detector, photomixers, and optoelectronic mixers and switches are paramount examples of our devices with applications ranging from fiber-optic quantum cryptography to live-cell imaging and spectroscopy.
