CAREER: Advanced Materials for Photonics

建议的活动是根据受影响的学生群体组织的，从研究生到学龄前学生。保持对尖端技术的积极研究计划将使真正适用的课程被带到每个年龄组。在研究生教育方面，P1将继续教授一门名为“薄膜技术原理”的课程，并将在未来5年内专注于两个具体目标。一个是开发新的教科书，另一个是继续开发动手团队竞赛实验室。这两个目标是互补的，因为实验室手册将作为教科书的辅助出版。对于研究生研究，提议的工作旨在为集成光电路配备目前仅作为分立元件可用的重要器件。一个很好的例子是磁光隔离器，目前由掺杂钇铁石榴石（YIG）组成，由于其延长了激光寿命，已被引用为光纤系统中最重要的部件。如果隔离器可以直接集成到光源中，将大大减少在光学系统中添加隔离器的尺寸、重量和成本。在这里，利用先前NSF支持奠定的基础，集成隔离器将取得快速进展（该工作被邀请参加2001年Photonics West）。我们将研究各种磁光波导和永磁体膜，以便在未来五年内开发出几代集成隔离器。除了集成隔离器之外，拟议的工作将把P1的专业知识扩展到光子晶体的革命性领域。她已经开始在阳极氧化铝中生长纳米结构，并计划将这些结构应用于开发二维磁光子带隙材料。对于这种应用，纳米结构必须具有优异的周期性。使用一种新的气相沉积技术，结构将在电子显微镜下直接观察到它们的生长。这将使研究生长机制成为可能，以便在鼓励生长的同时抑制成核，从而扩大长程有序。然后，这些纳米结构将被用来制作隔离器工作中最好的磁光波导，以制造磁光子晶体。这项工作是革命性的，因为它为目前仅作为一维多层研究的磁光子晶体领域增加了一个新的维度。在本科教育和研究方面，当地大学设施使用计划将启动，MRS本科材料研究计划（由P1创建的计划）的支持将继续，P1系的NSF本科生研究经验计划将续期。NSF REU和明尼苏达大学的UROP项目都将用于支持本科生的研究项目。本科教学最初将采用背诵课的形式，以便P1能够了解她随后将教授的系里课程。最后，学前-12年级的科学推广将包括每年夏天聘请一名高中生与P1的小组一起工作，并为学前-12年级的小组开发和提供科学演示。作为一个代表性不足的群体的一部分，P1经常被要求向同一群体的年轻人进行这些示威。这种草根推广有望为科学招募更多的优秀学生。

The proposed activities are organized according to the impacted student group from graduate down to preschool students. Maintaining an active research program on the cutting edge of technology will enable truly applicable lessons to be brought to each age group.Towards graduate education, the P1 will continue to teach a course entitled "Principles of Thin Film Technology," and will focus on two specific goals over the next 5 years. One is the development of a new textbook and the other is the continued development of hands-on team-competition laboratories. These two goals are complimentary in that a laboratory manual will be published as an ancillary to the textbook.Towards graduate research, the proposed work aims to equip integrated optical circuits with important devices that are currently available only as discrete components. A great example would be magneto-optical isolators, currently composed of doped yttrium iron garnet (YIG), which have been cited as the most important components in fiber optic systems due to their extension of laser lifetimes. The size, weight and cost of adding an isolator to an optical system would be greatly reduced if the isolator could be integrated directly into the optical source. Here, rapid progress will be made toward integrated isolators using the foundation laid by prior NSF support (work invited to Photonics West 2001). Various magneto-optical waveguides and permanent magnet films will be investigated so that several generations of integrated isolators will be developed over the next five years.In addition to integrated isolators, the proposed work will extend P1's expertise into the revolutionary field of photonic crystals. She has started growing nanostructures in anodized alumina and plans to apply these structures to develop 2D magnetophotonic bandgap materials. For this application, the nanostructures must have excellent periodicity. Using a novel vapor deposition technique, the structures will be observed directly in an electron microscope as they grow. This will enable investigations of the growth mechanisms so that nucleation can be suppressed while growth is encouraged, resulting in extended long range order. These nanostructures will then be used to pattern the best magneto-optical waveguides from the isolator work in order to make magnetophotonic crystals. This work is revolutionary in that it adds a new dimension to the current field of magnetophotonic crystals, which are presently only studied as one-dimensional multilayers.Towards undergraduate education and research, a Local College Facilities Usage Program will be inaugurated, support of the MRS Undergraduate Materials Research Initiative (a program founded by the P1) will continue, and the NSF Research Experiences for Undergraduates Program in the P1's department will be renewed. Both the NSF REU and the University of Minnesota's UROP programs will be used to support undergraduate research projects. Undergraduate teaching will take the form of recitations initially so that the P1 can learn about the departmental courses that she will subsequently teach.Finally, preschool-12th grade science outreach will include hiring a high school student to work with P1's group every summer, and developing and delivering science demonstrations to preschool-12th grade groups. As part of an underrepresented group, the P1 is often asked to deliver these demonstrations to youth of the same group. This grassroots outreach has promise for recruiting additional good students to science.
