Project summaryWe propose the acquisition of a picosecond streak camera system for time-resolvedmeasurements of photoluminescence from semiconductor nanostructures. The equipment will belocated in the PIs optics laboratory in Ginzton, where it would be completely accessible to theco-PIs and their students residing in the same building, as well as to the interested users fromother research groups around Stanford. Ginzton Laboratory has a strong infrastructure fornanophotonics research, including state-of-the-art optics laboratories of the investigators and ashared microfabrication facility. In addition, the Stanford Nanofabrication Facility is located inthe neighboring building and is extensively used by the investigators. The streak camera willcomplement the existing capabilities of the PIs and broaden their research in the fields ofnanoscale photonics and quantum information processing, which are already major thrusts in theGinzton Laboratory. Moreover, the camera will enable research training of a large number ofgraduate and undegraduate students from the research groups of the investigators in performingtime-resolved spectroscopy and will thus be important in education of a new generation ofscientists who will exploit nanophotonics at its full potential. The PIs also place an emphasis onresearch training of women and other underrepresented groups; for example, there are usuallyaround 10 women researchers (mainly experimentalists) across their groups.The streak camera system is capable of unprecedented sensitivity in performing time-resolvedphotoluminescence measurements. If the NSF decides to fund this project, the activity that wouldresult would be time-resolved study of light emitted from photonic nanostructures (e.g., photoniccrystal structures) with embedded emitters, such as excitons in quantum dots or quantum wellimpurities. This is crucial for development of novel low-threshold and high-speed lasers andoptical modulators, as well as hardware for emerging technologies such as quantum computationand quantum communication (e.g., single and entangled photon sources and photon storagecomponents). PIs are presently leading research programs focused on quantum informationprocessing in the optical domain and on development of optical interconnects; these programswould also greatly benefit from the acquisition of the proposed equipment.

项目摘要我们建议收购皮秒条纹相机系统的时间分辨测量半导体纳米结构的光致发光。这些设备将被安置在位于Ginzton的PI光学实验室，在那里，它将完全被居住在同一栋楼里的生态PI和他们的学生以及来自斯坦福大学周围的研究小组的感兴趣的用户所使用。金兹顿实验室拥有强大的纳米光子学研究基础设施，包括最先进的研究人员光学实验室和共享的微加工设施。此外，斯坦福大学的纳米纤维实验室位于邻近的建筑物内，被研究人员广泛使用。条纹相机将补充PI的现有能力，并扩大他们在纳米光子学和量子信息处理领域的研究，这已经是金兹顿实验室的主要推动力。此外，相机将使大量的研究生和本科生的研究培训，从研究小组的调查人员在执行时间分辨光谱，因此将是重要的教育新一代的科学家谁将利用纳米光子学在其全部潜力。PI还强调对女性和其他代表性不足的群体进行研究培训;例如，他们的团队通常有大约10名女性研究人员（主要是实验人员）。条纹相机系统在执行时间分辨光致发光测量方面具有前所未有的灵敏度。如果美国国家科学基金会决定资助这个项目，那么结果将是对光子纳米结构发射的光进行时间分辨研究（例如，光子晶体结构），其具有嵌入的发射体，例如量子点或量子阱中的激子。这对于开发新型低阈值和高速激光器和光调制器以及量子计算和量子通信等新兴技术的硬件至关重要（例如，单光子源和纠缠光子源以及光子存储部件）。PI是目前领先的研究计划，专注于光域量子信息处理和光互连的发展;这些计划也将大大受益于拟议设备的收购。
