0321449HudgingsJust as the dramatic success of ever more complex silicon integrated circuits has required the development of strategies for detailed on-chip testing and wafer-scale probing, future progress in complex photonic integrated circuits (PICs) will rely on the development of non-invasive techniques for wafer-scale optical profiling of integrated optoelectronics. This proposal is to develop thermoreflectance techniques that will allow us unprecedented access into the propagation of light within complex photonic circuits. The PI will develop a thermal profiling technique using thermoreflectance imaging in combination with a new total energy balance model for external heat exchange that will enable non-contact, three-dimensional thermal imaging with spatial resolution on the order of 100 nm, less than 1 ms temporal resolution, and temperature resolution of 1-100 mK. This is an order of magnitude better than commercial IR microscopes, and it is much faster than liquid crystal thermometry. This state of the art technique will enable the PI to achieve the following technological advances: 1) Noninvasive optical profiling of PICs, 2) Development of a novel technique for extracting carrier temperature distribution from lattice surface temperatures of optoelectronic devices, 3) Three-dimensional thermal imaging, and 4) Measurement of thermal transients inside working optoelectronic devices.This proposal will significantly enhance the infrastructure for research and education by creating a partnership between Mount Holyoke College, a top-20 undergraduate liberal arts college for women and MIT, one of the world's premier technical universities. Furthermore, the proposal integrates research with education at all levels of study: over the duration of the three year research plan, 6-8 undergraduate women students from Mount Holyoke will work on this project, in collaboration with a graduate student from MIT. Mt Holyoke places a particular premium on the integration of cutting-edge research into the education of the next generation of women scientists and engineers, so undergraduates will be heavily involved in all aspects the proposed research. Finally, because Mt Holyoke is a women's college with an unusually diverse student body, the proposed research comprises a remarkable opportunity to broaden the participation of underrepresented students in science.

就像更复杂的硅集成电路的巨大成功需要开发详细的芯片上测试和晶片规模探测的策略一样，复杂光子集成电路(PIC)的未来发展将依赖于集成光电子产品晶片规模光学轮廓的非侵入性技术的开发。这项提议是为了开发热反射技术，使我们能够史无前例地进入复杂光子电路中的光传播。PI将开发一种使用热反射成像的热成像技术，并结合新的外部热交换总能量平衡模型，实现空间分辨率为100 nm、时间分辨率低于1ms、温度分辨率为1-100mK的非接触式三维热成像。这比商用红外显微镜好一个数量级，而且比液晶测温快得多。这项最先进的技术将使PI能够实现以下技术进步：1)PIC的非侵入性光学轮廓，2)开发一种从光电设备的晶格表面温度中提取载流子温度分布的新技术，3)三维热成像，以及4)测量工作中的光电设备内部的热瞬变。这项建议将通过在曼荷莲学院和麻省理工学院之间建立合作伙伴关系，显著增强研究和教育的基础设施。芒特霍利奥克学院是一所排名前20的文科女性本科学院，麻省理工学院是世界一流的技术大学之一。此外，该提案将研究与各级教育相结合：在三年研究计划期间，曼荷莲大学的6-8名本科生将与麻省理工学院的一名研究生合作开展这一项目。Mt Holyoke特别重视将尖端研究融入下一代女科学家和工程师的教育中，因此本科生将大量参与拟议研究的所有方面。最后，由于霍利约克山是一所女子学院，学生群体异乎寻常地多样化，拟议中的研究包含了一个极好的机会，可以扩大未被充分代表的学生在科学领域的参与。
