Abstract Title: Glass-based flexible integrated photonic devicesAbstract:Conventional integrated photonic devices are fabricated almost exclusively on rigid substrates such as silicon wafers. The proposed program aims to develop the fundamental optical physics and device processing know-how that enable photonic integration on unconventional flexible plastic substrates. By imparting mechanical flexibility to photonic structures, the research will advance understanding into optical and mechanical interaction mechanisms in the nanoscale, and open up emerging application venues including humanlike robotic skins, prosthetic limbs, minimally invasive surgical tools, and touch panels for flexible consumer electronics. The scientific research will be tightly integrated with curriculum development, undergraduate student training, and development of hands-on modules for optics education. Research outcome from the project will be incorporated into a new course on amorphous materials the PI will develop. In addition to augmenting classroom education at MIT, the program will also promote the free sharing and distribution of knowledge by developing online courses through the edX initiative. The participating undergraduate and graduate researchers will benefit from the interdisciplinary research as well as cross-cutting collaborations to extend their technical experiences. The program will also develop hands-on modules for K-12 students and the general public to promote public awareness of optical sciences and nanotechnology through working with the MIT Edgerton Center and local museums.Flexible photonics is uniquely poised at the nexus between photonics, mechanics, and materials sciences. While previously the topic has largely been explored from the three isolated fields, the proposed research will pioneer an interdisciplinary approach synergistically combining innovative photonic design, nano-mechanical engineering, and unconventional material processing to unravel the rich physics underlying tensorial strain-optical interactions and apply the principle to multidirectional stress measurement. Glasses, the backbone materials for lenses and fibers, will be explored as the preferred optical materials for photonic integration onto unconventional plastic substrates exploiting their low optical losses and extreme processing versatility, as they can be monolithically deposited on virtually any technically important substrate and can be shaped into functional device forms via traditional lithography or soft lithographic methods including molding, imprint, and ink jet printing. Further, while traditional planar photonic circuits on flat substrates are 2-D in nature, the proposed research will utilize the additional geometric degrees of freedom conferred by mechanical flexibility to create a 3-D photonics platform based on planar microfabrication, a technology that will enable pinpointing light-matter interaction locations in a 3-D space inaccessible to conventional "flat" photonics and thus will have immense application potentials for sensing, communications, and imaging.

摘要标题：基于玻璃的柔性集成光子设备的摘要：常规的集成光子设备几乎完全在刚性基板（例如硅晶片）上制造。拟议的计划旨在开发基本的光学物理和设备处理知识，以实现非常规柔性塑料底物的光子整合。通过将机械灵活性赋予光子结构，该研究将提高纳米级的光学和机械相互作用机制的理解，并为包括人类的机器人皮肤，假体肢体，微创的庞然大物工具以及灵活消费电子电子设备的触摸面板开放新兴的应用场所。科学研究将与课程开发，学生培训本科生培训以及用于光学教育的动手模块的开发紧密融合。该项目的研究结果将纳入PI将开发的有关无定形材料的新课程中。除了增加麻省理工学院的课堂教育外，该计划还将通过EDX计划开发在线课程来促进知识的自由共享和分发。参与的本科生和研究生研究人员将从跨学科研究以及跨剪裁合作中受益，以扩展其技术经验。该计划还将为K-12学生和公众开发动手模块，以通过与MIT Edgerton中心和当地博物馆合作，以促进公众对光学科学和纳米技术的认识。FlixiblePhotonics在光子，力学和材料科学之间的Nexus中有着独特的依据。虽然以前的主题已经从三个孤立的领域进行了很大的探讨，但拟议的研究将开创一种跨学科的方法，以协同结合创新的光子设计，纳米机械工程以及非常规的材料处理，以揭示富裕物理学的良好物理学的紧张互动相互作用，并将其原理应用于多次衡量。玻璃是镜头和纤维的骨干材料，将被探索为光子整合到非常规的塑料基板上的首选光学材料，这些材料利用了低光学损失和极端处理的多功能性，因为它们可以单数地沉积在几乎任何技术上重要的底物上，并可以通过墨水构造和墨水式的lith仪构成型号和软性矿石构图，并可以将其塑造到功能上。 Further, while traditional planar photonic circuits on flat substrates are 2-D in nature, the proposed research will utilize the additional geometric degrees of freedom conferred by mechanical flexibility to create a 3-D photonics platform based on planar microfabrication, a technology that will enable pinpointing light-matter interaction locations in a 3-D space inaccessible to conventional "flat" photonics and thus will have immense application potentials for sensing, communications,和成像。
