MRI: Development of Magneto-Optic Near-field Scanning Optical Microscope (MO-NSOM) for optical characterization of nanostructures

磁共振成像：用于纳米结构光学表征的磁光近场扫描光学显微镜(MO-NSOM)的发展利用可见光或近可见光的光学方法可能是几乎所有科学领域中最流行的样品表征工具。近场显微镜(NSOM)可以克服衍射极限，但代价是更复杂的仪器，这阻碍了纳米尺度上的光学表征。目前，还没有提供皮秒时间和纳米空间分辨率的偏振敏感检测的仪器。智力优势：这一提议将开发一种磁光近场扫描光学显微镜(MO-NSOM)。这将是第一台集纳米空间分辨率、亚皮秒时间分辨率和偏振灵敏度于一体的仪器。为了实现这一目标，PIS将与两个行业合作伙伴合作，显著扩大从光源到检测仪器等所有相关领域的商用显微镜的能力。他们将开展一系列不同的研究项目，重点是密集阵列中单个纳米磁结构的超快纳米磁光。广泛影响：皮秒MO-NSOM将是纳米尺度表征仪器的宝贵补充，它结合了一大套可单独使用或组合使用的功能。开发工作的结果将通过参与的公司和在PI的网站上发布。研究生和本科生都将参与仪器开发的不同方面。此外，该仪器还将用于加州大学圣克鲁斯分校电气工程系的课程开发。

MRI: Development of Magneto-Optic Near-field Scanning Optical Microscope (MO-NSOM) for optical characterization of nanostructuresOptical methods using visible or near-visible light are perhaps the most popular tools for sample characterization across virtually all scientific fields. Optical characterization on the nanoscale is hampered by the diffraction limit which can be overcome with near-field microscopy (NSOM), but at the price of more complex instrumentation. At this time, no instrument exists that provides polarization-sensitive detection with picosecond temporal and nanometer spatial resolution.Intellectual merit: This proposal will develop a Magneto-Optic Near-field Scanning Optical Microscope (MO-NSOM). This will be the first instrument that combines nanometer spatial resolution, sub-picosecond temporal resolution, and polarization sensitivity. To accomplish this goal, the PIs will work with two industrial partners to significantly expand the capabilities of a commercially available microscope in all relevant areas ranging from light source to detection apparatus. They will carry out a diverse range of research projects, focusing on ultrafast nano-magneto-optics of individual nanomagnetic structures in dense arrays.Broader impact: The picosecond MO-NSOM will be a valuable addition to nanoscale characterization instrumentation that combines a large set of capabilities that can be used individually or in combination. The results of the development effort will be disseminated through the participating companies and on the PI's website. Both graduate and undergraduate students will be involved in different aspects of the instrument development. In addition, the instrument will be used for course development in the Electrical Engineering department at UC Santa Cruz.
