Objective:The objective is to develop all-optical switching that will fundamentally transform optical communications for sustainability and scalability, with ambitious goals of very low switching energy, loss, and suitable for chip-scale integration. Intellectual Merit:The intellectual merit includes the invention of a new platform to revolutionize chip-scale integrated optics, and, in particular, all-optical switching. The platform uses a new concept of hollow-core waveguide guided by two parallel ultra-thin layers of high index contrast grating (HCG). The HCG has an extraordinary low-loss guiding mechanism which leads to three orders of magnitude reduction in the volume of the switch medium, resulting in orders of magnitude lower switching energy, high speed and broad bandwidth. This new platform will lead to new physics and major implications for integrated optoelectronic circuits. Broader Impacts:The proposed cross-disciplinary research will bridge between devices, systems and optical networks. The PI is a member of the Center for Integrated Access Networks, an NSF ERC with a vision is to create transformative technologies for optical access networks. This proposed research topic will enhance the on-going collaboration between PI and ERC participants. The PI has on-going collaborations with industry and international institutes for students to interact with a wide research community. These interdisciplinary collaboration will provide better preparation for students with real world applications and research experiences. The PI is active in outreaching to high school students and undergraduates from disadvantaged communities or under-represented minorities. The education program focuses on close connection between the outreach activities and cutting-edge research

目标：目标是开发全光开关，从根本上改变光通信的可持续性和可扩展性，具有非常低的开关能量，损耗和适合芯片级集成的雄心勃勃的目标。 智力优势：智力优势包括发明了一个新的平台，以彻底改变芯片级集成光学，特别是全光开关。 该平台采用了一种新的概念，即由两个平行的超薄层高折射率对比度光栅（HCG）引导的空芯波导。 HCG具有非凡的低损耗引导机制，其导致开关介质的体积减小三个数量级，从而导致数量级更低的开关能量、高速和宽带宽。 这个新平台将导致新的物理和集成光电子电路的重大影响。 更广泛的影响：拟议的跨学科研究将在设备、系统和光网络之间架起桥梁。PI是集成接入网络中心的成员，该中心是NSF ERC，其愿景是为光接入网络创建变革性技术。这个拟议的研究课题将加强PI和ERC参与者之间的持续合作。 PI与行业和国际研究机构持续合作，让学生与广泛的研究社区互动。 这些跨学科的合作将为学生提供更好的准备与真实的世界的应用和研究经验。 PI积极向来自弱势社区或代表性不足的少数群体的高中生和大学生进行外联。 教育计划的重点是外展活动和前沿研究之间的密切联系
