AbstractECCS-0801922T. Huang, PA ST U University Park Objective: The proposal focuses on developing a new class of ultra-small, all-optical plasmonic switches using photoactive rotaxanes as active components. The proposed photoactive rotaxane-based all-optical plasmonic switches could achieve unprecedented performance (size: molecular level; energy consumption: 1-2 eV; excellent reversibility and flexibility) and be integral components for the future ultra-small, ultra-fast plasmonic circuits and very large scale electronics and photonics integration (VLSEPI). Intellectual merits: This project introduces light-driven molecular machines into optical device settings. Molecular machines driven by light have several advantages: they can be switched much faster; they do not produce any waste; light can be used for dual purposes¡Vinducing (writing) as well as detecting (reading) molecular motions. Experimental and numerical investigations will shed some light on the fundamental understanding of controlling plasmonics at molecular level. More importantly, with molecular machines¡¦ advantages in their size, energy consumption, speed, and controllability at molecular level, we expect that once established, the proposed rotaxane-based plasmonic switches will be welcomed in many applications such as optical communication. Broader Impact: The PI will partner with the Penn State Center for Nanoscale Science and develop outreach activities around the theme of ¡¥from molecular shuttles to nanomechanics, nanoelectronics, and nanophotonics¡¦. A suite of demonstrations will imitate molecular machines¡¦ mechanical motions, broadly constructed and idealized in their operation by macroscopic models. The results developed in the past as well as from this proposal will be used to illustrate what molecular machines can achieve, and they will be delivered to museums, high-schools, and summer programs.

摘要ECCS-0801922 T。Huang，PA ST U大学公园目标：该提案的重点是开发一类新的超小型全光学等离子体开关，使用光敏轮烷作为活性组分。所提出的基于光敏轮烷的全光等离子体开关可以实现前所未有的性能（尺寸：分子水平;能量消耗：1-2 eV;优异的可逆性和灵活性），并且是未来超小、超快等离子体电路和超大规模电子学和光子学集成（VLSEPI）的不可或缺的组件。智力优势：该项目将光驱动分子机器引入光学设备设置。由光驱动的分子机器有几个优点：它们可以更快地转换;它们不产生任何废物;光可以用于双重目的-诱导（写入）以及检测（阅读）分子运动。实验和数值研究将揭示一些基本的理解控制等离子体在分子水平上。更重要的是，由于分子机器在尺寸、能耗、速度和分子水平的可控性方面的优势，我们预计一旦建立，基于轮烷的等离子体开关将在光通信等许多应用中受到欢迎。更广泛的影响：PI将与宾夕法尼亚州立大学纳米科学中心合作，围绕“从分子航天飞机到纳米力学、纳米电子学和纳米光子学”的主题开展外联活动。 一套演示将模仿分子机器的机械运动，广泛构建和理想化的宏观模型在其操作。 过去和本提案中开发的结果将用于说明分子机器可以实现的目标，并将交付给博物馆、高中和暑期项目。
