Acquisition of a Picosecond Streak Camera System for Time-Dependent Luminescence Measurements of Semiconductor Nanostructures

我们提出了一种皮秒条纹相机系统，用于半导体纳米结构的光致发光的时间分辨测量。该设备将放置在PIs位于Ginzton的光学实验室中，在那里，住在同一栋楼的PIs和他们的学生，以及斯坦福大学周围研究小组的感兴趣的用户都可以完全使用它。Ginzton实验室拥有强大的纳米光子学研究基础设施，包括研究人员的最先进的光学实验室和共享的微加工设备。此外，斯坦福纳米制造设施位于邻近的大楼内，被研究人员广泛使用。条纹相机将补充pi的现有能力，并扩大他们在纳米级光子学和量子信息处理领域的研究，这已经是ginzton实验室的主要推动力。此外，该相机将使大量来自研究人员研究小组的研究生和本科生能够进行时间分辨光谱学的研究培训，因此对新一代科学家的教育很重要，他们将充分利用纳米光子学的潜力。项目还强调对妇女和其他代表性不足群体的研究培训；例如，她们的团队中通常有大约10名女性研究人员（主要是实验人员）。条纹相机系统在进行时间分辨光致发光测量时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，那么将产生的活动将是对具有嵌入式发射器的光子纳米结构（例如光子晶体结构）发出的光的时间分辨研究，例如量子点或量子井纯度中的激子。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（例如，单光子源和纠缠光子源以及光子存储组件）的硬件至关重要。pi目前是光学领域量子信息处理和光互连发展的主要研究项目；这些计划也将大大受益于拟议设备的采购。

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.
