ECS-0636677H。该计划是一项合作和跨学科的努力，旨在开发无线和光网络之间的无缝接口，而不受射频载波频率、信道带宽和数据调制格式的影响。智力优势：广泛的技术目标是促进对基本知识的理解，并在光和微波混合系统之间的接口上产生显著的性能提升。我们将开发技术，促进混合射频和光子集成电路在芯片级别的集成，提高性能，缩小元件尺寸，并提供惊人的新功能。要实现这一点，必须促进两个域之间的双向流量，将流量从RF载波无缝转换为光载波，透明地适应各种比特率和调制格式，处理远远超过任何先前报道的RF-光链路的数据容量，并在这种混合RF+光接口中展示能效。将研究涉及SOI中的频谱效率、业务粒度、传输损伤、RF CMOS集成和芯片级光学元件的技术挑战。广泛影响：拟议研究主题的独特性质涉及多个学科，如半导体器件、光子学、集成电路、通信理论、无线和有线系统，以及混合RF+光学器件的制造。将开设若干与研究课题有关的研究生和本科生课程，其中许多课程是通过远程教育网(DEN)为校外学生和研究人员提供外联服务的。我们将举办内部和外部由学生组织的研讨会/工作坊，向学术界和工业界更广泛的受众传播拟议研究的成果。

ECS-0636677H. Hashemi, Univ of Southern CaliforniaThe proposed program is a collaborative and interdisciplinary effort to develop a seamless interface between wireless and optical networks irrespective of RF carrier frequency, channel bandwidth, and data modulation format.Intellectual Merit: The broad technical goals are to advance the fundamental understanding and produce dramatic performance increases at the interface between optical and microwave hybrid systems. We will develop technology that facilitates the integration of hybrid RF and photonic integrated circuits at the chip level with improved performance, reduced component size, and dramatic new functionality. To accomplish this, it will be necessary to facilitate bi-directional traffic between the two domains, seamlessly convert traffic from an RF carrier wave into an optical carrier wave, transparently accommodate various bit-rates and modulation formats, process data capacities that are well in excess of any previously reported RF-optical link, and demonstrate energy efficiency in this hybrid RF+optical interface. Technical challenges involving spectral efficiency, traffic granularity, transmission impairments, RF CMOS integration, and chip-scale optical components in SOI will be studied.Broader Impact: The unique nature of the proposed research topic involves multiple disciplines such as semiconductor devices, photonics, integrated circuits, communication theory, wireless and wireline systems, and fabrication of hybrid RF+optical devices. Several graduate and undergraduate level courses related to the research topic will be offered, many of which through the Distance Education Network (DEN) to provide outreach for off-campus students and researchers. We will have internal and external student-organized seminars/workshops to disseminate outcomes of the proposed research to a broader audience in academia and industry
