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.

Project Summarywe提出，从半导体纳米结构中获取Picsecond Streak摄像头系统，以进行光致发光的时间分辨测量。该设备将在Ginzton的PIS光学实验室中占据，居住在同一座建筑物中的Theco-Pis以及他们的学生以及斯坦福各地的其他研究小组的感兴趣用户都可以完全使用。 Ginzton实验室拥有强大的基础设施富诺型研究，包括研究人员的最先进的光学实验室和Ashared Microwrication设施。此外，斯坦福大学纳米制造设施位于相邻的建筑物中，并被调查人员广泛使用。条纹摄像头将逐步计算PIS的现有功能，并在纳米级光子学和量子信息处理领域扩大其研究，这已经是Theginzton实验室中的主要推力。此外，该相机将使研究人员的大量研究生和未培养的学生能够在表演时间分辨光谱方面进行研究培训，因此对于将在其全部潜力中利用纳米光子学的新一代的学家教育很重要。 PI还强调了对妇女和其他代表性不足的群体的研究培训。例如，通常在其组中有10位女性研究人员（主要是实验者）。条纹摄像头系统能够在执行时间固定的闪光发光测量方面具有前所未有的灵敏度。如果NSF决定为该项目提供资金，那么将会产生的活性将是对光子纳米结构（例如光子晶体结构）发出的光的时间研究，这些光（例如，光子晶体结构）带有嵌入式发射器，例如量子点或量子良好的量子的激子。这对于开发新型的低阈值和高速激光器和光度调节器以及用于新兴技术（例如量子计算和量子通信）的硬件至关重要（例如，单个和纠缠的光子源和光子storageagecomponents）。 PI目前是主要的研究计划，侧重于光学域中的量子信息处理和光学互连的开发；这些程序也应大大受益于拟议的设备。
