Title: Development of Optoelectronic Devices for the Far-InfraredGeneral Abstract: The objective of this research effort is to develop optical materials and devices that control and emit far-infrared (far-IR) light with wavelengths between 20-60ìm. There are a number of important applications for light in this wavelength range, ranging from imaging for astronomy and cosmology efforts and sensing of aromatic hydrocarbons, asphaltenes, and biological materials. However, the far-IR is an extremely challenging wavelength range to work in, with little to no optical infrastructure for either conducting fundamental research or developing optical devices and systems, making the far-IR arguably one of the few remaining frontiers of the electromagnetic spectrum. The challenges of the far-IR largely stem from the lattice vibrations (phonons) of most of the semiconductors used for optoelectronic devices across the electromagnetic spectrum. In the far-IR, phonons strongly absorb light and conventional device designs are no longer appropriate. In this program we will look to harness these lattice vibrations and utilize them to generate electromagnetic radiation, or light. In doing so, we will develop an architecture for engineering designer far-IR materials and emitters that incorporate unique light-matter interactions in an oft-neglected portion of the optical spectrum, resulting in an optical toolkit for the far-IR and a new generation of optical devices. At the same time, we will undertake both educational and outreach efforts, as well as a coherent effort to grow the visibility and impact of far-IR optoelectronics research, which has no agreed-upon dissemination systems (journals, conferences, workshops), commercial vendors, or even nomenclature. Technical Abstract: Technological developments over the past several decades have significantly increased our ability to generate, control, and detect electromagnetic (EM) radiation across an ever-increasing range of wavelengths. Much of this progress has been spurred by the rapid growth of semiconductor optoelectronic technologies. Yet the far-infrared (far-IR, 20-60 ìm) wavelength range has not shared in this explosive growth. Ironically, a primary reason for the lack of progress in the far-IR lies in the semiconductor crystal lattice itself: characteristic vibrations of the lattice, known as phonons, interact strongly with far-IR light and result in strong optical absorption. This program aims to explore and develop a set of technologies, materials, and phenomena which will serve as the technical foundation of an optical infrastructure for the largely undeveloped far-IR wavelength range. In particular, we propose to develop optical materials and opto-phononic-electronic (OPE) devices that control and emit far-IR light by engineering electronic transport, surface waves, and the interaction of these surface waves with bulk optical phonons. In doing so, we will develop an architecture for engineering designer far-IR materials and OPE emitters that incorporate unique light-matter interactions in an oft-neglected portion of the optical spectrum, resulting in an optical toolkit for the far-IR and a new generation of optical devices. Concurrent with the technical thrusts of the proposed effort, we will: i) bring STEM-based activities into K12 classrooms and after-school programs and ii) work to cultivate an intellectual community with a shared interest in the far-IR by means of virtual communities and special issues in peer-reviewed publications.

职务名称：远红外光电器件的发展概述：本研究工作的目的是开发控制和发射波长在20- 60 μ m之间的远红外（远IR）光的光学材料和器件。 在这个波长范围内的光有许多重要的应用，从天文学和宇宙学的成像工作和芳香烃，沥青质和生物材料的传感。然而，远红外是一个极具挑战性的波长范围，几乎没有光学基础设施用于进行基础研究或开发光学设备和系统，这使得远红外可以说是电磁频谱中为数不多的前沿之一。 远红外的挑战主要来自于电磁光谱中用于光电器件的大多数半导体的晶格振动（声子）。 在远红外中，声子强烈吸收光，传统的器件设计不再合适。 在本计划中，我们将寻求利用这些晶格振动并利用它们来产生电磁辐射或光。 在这样做的过程中，我们将为工程设计师开发一种远红外材料和发射器的架构，这些材料和发射器将独特的光-物质相互作用纳入光谱中经常被忽视的部分，从而为远红外和新一代光学器件提供光学工具包。 与此同时，我们将开展教育和推广工作，以及一致的努力，以提高远红外光电子学研究的知名度和影响力，该研究没有商定的传播系统（期刊，会议，研讨会），商业供应商，甚至命名。 技术摘要：过去几十年的技术发展显著提高了我们在不断增加的波长范围内产生，控制和检测电磁（EM）辐射的能力。这些进展大部分是由半导体光电子技术的快速发展所推动的。然而，远红外（远红外，20-60微米）波长范围并没有分享这种爆炸性增长。 具有讽刺意味的是，远红外线缺乏进展的主要原因在于半导体晶格本身：晶格的特征振动，称为声子，与远红外线强烈相互作用，导致强烈的光吸收。 该计划旨在探索和开发一系列技术，材料和现象，这些技术，材料和现象将作为远红外波长范围内光学基础设施的技术基础。 特别是，我们建议开发光学材料和光-声-电（OPE）器件，通过工程电子输运，表面波，以及这些表面波与体光学声子的相互作用来控制和发射远红外光。 在此过程中，我们将为工程设计师开发远红外材料和OPE发射器的架构，这些材料和OPE发射器将独特的光-物质相互作用纳入光谱中经常被忽视的部分，从而为远红外和新一代光学器件提供光学工具包。 与拟议工作的技术重点同时，我们将：i）将基于STEM的活动纳入K12教室和课后计划，ii）通过虚拟社区和同行评审出版物中的特殊问题，努力培养一个对远红外有共同兴趣的知识社区。
