项目摘要

Progress in the fields of materials science, nanotechnology, healthcare, and communications all require precise control and understanding of light interaction with nanoscale objects. Unfortunately, the phenomenon known as the diffraction limit prevents focusing of light to areas smaller than approximately half the wavelength of the light. For thermal (mid-infrared) radiation, the diffraction limit-scale is roughly five microns, much larger than 10-100’s-nanometer size of semiconductor electronic components, viruses, and other objects of interest. In this collaborative research the investigators develop novel structures, photonic funnels, that eliminate the diffraction limit and efficiently guide the optical signals between free space and nano-scale areas. Theoretically, the investigators develop equations and computer codes to model propagation of light through the funnels, as well as the emission of light by nanoscale objects positioned within, and in proximity to, the funnels. Experimentally, the researchers develop procedures to fabricate the funnels, integrate light emitters, and analyze light propagation through, and from, these structures. The exploration and development of these novel composite materials have the potential to open new avenues in high-resolution probing of biological, electronic, and optical structures, and in engineering optical interactions with these structures. In addition, the investigators plan for outreach and educational activities aimed at both high-school and college-level students, as well as personnel exchange and training across the disciplines.This collaborative project aims to address one of the fundamental limits of light-matter interaction, the diffraction limit. The research team utilizes recently developed composite optical materials with highly doped plasmonic inclusions, hyperbolic metamaterials, and develops tools for the design, fabrication, and analysis of conical structures with hyperbolic cores, photonic funnels, in the important mid-infrared frequency range. The strong dielectric anisotropy of hyperbolic materials postpones the onset of the diffraction limit inside the funnels and thus enables propagation of light between micro- and nano-scales. The research team analyzes, theoretically and experimentally, light-matter interaction inside, and in close proximity to, the photonic funnels. Specifically, the team develops theoretical tools capable of accurate modelling of light generation from within, and in the near field of, the funnels, as well as of light propagation through the funnels. In parallel, the team develops fabrication and characterization procedures to accurately control the geometry of the funnels and to understand their optical response. The collaborative feedback within the team enables comprehensive development of a novel material platform offering unique opportunities for light manipulation.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

材料科学、纳米技术、医疗保健和通信领域的进步都需要精确控制和理解光与纳米级物体的相互作用，不幸的是，被称为衍射极限的现象阻止了光聚焦到小于大约一半波长的区域。对于热（中红外）辐射，衍射极限尺寸大约为 5 微米，比研究人员在这项合作研究中开发的半导体电子元件、病毒和其他感兴趣物体的 10-100 纳米尺寸大得多。新颖的结构——光子漏斗，可以消除衍射极限并有效地引导自由空间和纳米级区域之间的光信号。理论上，研究人员开发了方程和计算机代码来模拟光通过漏斗的传播以及光的发射。通过实验，研究人员开发了制造漏斗、集成光发射器并分析通过和来自这些结构的光传播的程序。新型复合材料有可能在生物、电子和光学结构的高分辨率探测以及与这些结构的光学相互作用方面开辟新的途径。此外，研究人员计划针对高中开展外展和教育活动。该合作项目旨在解决光与物质相互作用的基本限制之一——衍射极限。该研究团队利用最近开发的高掺杂复合光学材料。等离子体包裹体，双曲超材料，并开发了用于设计、制造和分析具有双曲核、光子漏斗的锥形结构的工具，在重要的中红外频率范围内，双曲材料的强介电各向异性推迟了漏斗内衍射极限的出现。从而使光在微米和纳米尺度之间传播，在理论上和实验上，光与物质在光子漏斗内部和附近的相互作用。与此同时，该团队开发了理论工具，能够对漏斗内部和近场中的光产生以及通过漏斗的特定几何形状的光传播进行精确建模，并了解其光学响应。团队内部的协作反馈使得能够全面开发反映光操纵独特机会的新型材料平台。该奖项符合 NSF 的法定使命，并且通过使用基金会的智力价值进行评估，被认为值得支持。以及更广泛的影响审查标准。
