项目摘要

0076322Houde-WalterThe Institute of Optics at the University of Rochester is building an excitation spectroscopy laboratory for research in new optical sources utilizing nano-engineered optical materials. An optical parametric oscillator, monochromator and multiscaler will be used in four research programs and two undergraduate/graduate training labs. Energy transfer will be studied using excitation spectroscopy to refine laser rate equation models and help to determine the best host composition and doping levels in rare-earth doped nano-glasses. In a related teaching lab exercise, students will observe cooperative luminescence in Yb-doped glasses, as is currently practiced in optical amplifier research. In another project, radiative impurity complexes will be introduced into silicon-on-insulator (SOI) structures that exhibit enhanced absorption/emission via nanostructured surfaces. Excitation spectroscopy will be used to elucidate the microscopic processes that determine emission cross sections in the hybridized SOI structures. Photoluminescence (PL) spectroscopy will be used to explore phonon mode control in isotopically pure crystalline Si. The new lab will permit the excitation of high spatial densities of indirect excitons, which may result in coherent phonon emission. Group III-V quantum dots, as made by in-situ laser patterning during molecular-beam epitaxial (MBE) growth, will also be investigated. Resonant excitation will be used to probe quantum dots of very narrow size distributions and may indicate the limit of what might be eventually achieved with an ensemble of uniform features. In a related lab, undergraduate students will investigate the absorption spectra of bulk crystals with various bandgaps (Si or GaAs, GaP, and GaN or diamond) as well as quantum well and dot group III-V semiconductors grown in our MBE lab. Honors students will also be encouraged to use the new lab for independent projects during their senior year.***The Institute of Optics at the University of Rochester, which grants Bachelors, Masters and doctoral degrees in Optical Science and Engineering, is building a new optical spectroscopy lab for research and training. New optical materials that utilize features on the nanometer (one billionth ofa meter) scale, will be emphasized. New training exercises that are closely related to this research will be offered to both undergraduate seniors and first-year graduate students. A tunable source and associated detection equipment will be used to probe the relationships between the microscopic components and their radiative efficiency. Improved knowledge and design of materials for many applications, including biomedical research and telecommunications, are expected. However, the overarching goal of this new laboratory is to reveal fundamental relations and elucidate hidden connections in the characterization and process parameters of new (or just useful) optical materials.%%%
0076322 Houde-Walter罗切斯特大学光学研究所正在建立一个激发光谱实验室,用于研究利用纳米工程光学材料的新光源。 光学参量振荡器,单色器和多定标器将用于四个研究项目和两个本科生/研究生培训实验室。 能量传递将使用激发光谱学来研究,以改进激光速率方程模型,并有助于确定稀土掺杂纳米玻璃中的最佳基质成分和掺杂水平。 在相关的教学实验练习中,学生将观察掺镱玻璃中的合作发光,就像目前在光放大器研究中所做的那样。 在另一个项目中,辐射杂质复合物将被引入绝缘体上硅(SOI)结构,通过纳米结构表面表现出增强的吸收/发射。激发光谱将用于阐明决定杂交SOI结构中发射横截面的微观过程。 光致发光(PL)光谱将用于探索声子模式控制同位素纯晶体硅。新实验室将允许激发高空间密度的间接激子,这可能导致相干声子发射。 III-V族量子点,在分子束外延(MBE)生长过程中,通过原位激光图案化,也将进行研究。 共振激发将用于探测非常窄尺寸分布的量子点,并可能表明最终可能通过均匀特征的集合实现的限制。 在相关的实验室,本科生将研究具有各种带隙(Si或GaAs,GaP和GaN或金刚石)的大块晶体的吸收光谱,以及在我们的MBE实验室生长的量子阱和点III-V族半导体。 荣誉学生也将被鼓励使用新的实验室在他们的高年级独立项目。罗切斯特大学的光学研究所赠款光学科学与工程学士、硕士和博士学位,该研究所正在建设一个新的光谱学实验室,用于研究和培训。 将强调利用纳米(十亿分之一米)尺度特征的新光学材料。 与本研究密切相关的新培训活动将提供给本科高年级学生和一年级研究生。 一个可调谐的源和相关的检测设备将被用来探测微观组件和它们的辐射效率之间的关系。 预计将有更多的知识和材料设计用于许多应用,包括生物医学研究和电信。 然而,这个新实验室的首要目标是揭示新(或只是有用的)光学材料的表征和工艺参数中的基本关系并阐明隐藏的联系。
