Wireless passive systems such as radio astronomy receivers, or atmospheric and geo-space science and climatological observation receivers are extremely sensitive to other active wireless interferences such as terrestrial cellular communications signals. As a result, they typically require dedicated radio frequency bands along with guard frequency bands around them. In many cases, active users may not physically co-exist in such areas, and many passive user infrastructures have therefore been built in remote areas. Such scenarios generally reduce the effective spectrum efficiency hindering the deployment of passive systems and creating barriers against future scientific discoveries. A new approach would be to allow both passive and active users to operate in adjacent frequency bands and in neighboring locations. This will allow active users to operate in previously unallowable guard frequency bands thereby significantly enhancing spectrum efficiency. This project introduces innovations on chip-scale microwave silicon photonics (SiP) adaptive filter architectures on the passive user side and passive-user-friendly protocols for resource allocation on the active (mobile) user side and thus addresses effective spectrum utilization/coexistence between passive and active (mobile) users. The research proposed in this project on microwave SiP filters along with wireless protocols can potentially revolutionize the future of wireless communication industries and provide further technological diversification for the photonic and semiconductor industries. Besides the technical impacts, the proposed project also promotes outreach activities to increase participation of students from underrepresented groups in science and engineering, including annual one-week summer camps for high school students. The research and educational results of this work will be disseminated to academic, industrial and government sectors.This project intends to develop (1) novel chip-scale microwave SiP reconfigurable/adaptive filter architectures on the passive user side, using a Silicon-on-Insulator (SOI) optical chip controlled by a nanometer Complementary Metal-Oxide Semiconductor (CMOS) SOI-chip that both allows for electrically controlled filter configuration and jammer rejection to dynamically protect passive users’ bands and (2) passive-user-friendly protocols for resource allocation on the active (mobile) user side. The research objectives are the development of: (1) a microwave SiP/CMOS adaptive filter architecture and its photonics/electronics components, along with algorithms/hardware for their automatic tuning on the passive user side, (2) online policies with provable service guarantees for the proposed passive-user-friendly protocol, and the (3) hybrid integration of the proposed adaptive filter on the passive user and resource allocation protocols in the active user sides using a test bench for verification of effective spectrum utilization. A versatile microwave SiP adaptive filter unit will be potentially connected to a passive user receiver in room temperature after the main antenna and low noise amplifier (either in room or cryogenic temperature). This unit includes highly selective reconfigurable SiP bandpass and notch filters to dynamically select the desired passive user band within 10-50 GHz range and reject active users as jammers. On the other hand, a passive-user-friendly protocol for resource allocation on the active (mobile) user side will be developed. This protocol will specifically consider both the sensitivity and linearity of the proposed electrooptic receiver on the passive user side, and the diverse features and service requirements of heterogeneous active user applications. Online algorithms with provable service guarantees will be developed for this protocol.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

无线无源系统，例如射电天文学接收器，大气和地理空间科学以及平民观察接收器对其他主动无线界面（例如陆地蜂窝通信信号）极为敏感。结果，他们通常需要专用的射频带以及周围的后卫频带。在许多情况下，活跃的用户可能不会在此类领域进行身体共存，因此，许多被动用户基础架构已在偏远地区构建。这种情况通常会降低有效的频谱效率阻碍了被动系统部署并为未来的科学发现造成障碍。一种新的方法是允许被动用户和活动用户在相邻的频带和相邻位置进行操作。这将使活跃的用户能够在先前不允许的防护频带中运行，从而显着提高频谱效率。该项目介绍了关于被动用户端的芯片尺度微波硅光子学（SIP）自适应滤波器体系结构，并在主动（移动）用户方面进行资源分配的被动用户友好型协议，因此解决了有效的频谱利用率/在被动和活跃（活动（移动）之间的频谱利用率/共存。该项目在微波sip过滤器以及无线协议上提出的研究可能会彻底改变无线通信行业的未来，并为光子和半导体行业提供进一步的技术多样性。除了技术影响外，拟议的项目还促进了外展活动，以增加代表性不足的科学和工程学的学生的参与，包括高中生的年度一周夏令营。这项工作的研究和教育结果将被传播到学术，工业和政府部门。 This project intends to develop (1) novel chip-scale microwave SiP reconfigurable/adaptive filter architectures on the passive user side, using a Silicon-on-Insulator (SOI) optical chip controlled by a nanometer Complementary Metal-Oxide Semiconductor (CMOS) SOI-chip that both allow for electrically controlled filter configuration and jammer rejection to dynamically protect passive users’ bands and （2）在活动（移动）用户端上用于资源分配的无源使用者友好型协议。 The research objectives are the development of: (1) a microwave SiP/CMOS adaptive filter architecture and its photonics/electronics components, along with algorithms/hardware for their automatic tuning on the passive user side, (2) online policies with provable service guarantees for the proposed passive-user-friendly protocol, and the (3) hybrid integration of the proposed adaptive filter on the passive user and resource使用测试工作台在活动用户方中的分配协议验证有效频谱利用率。在主天线和低噪声放大器（在室内或低温温度下），多功能微波SIP SIP自适应过滤器可能会在室温下在室温下与被动用户接收器连接。该单元包括高度选择性的可重新配置SIP带通和Notch过滤器，以动态选择10-50 GHz范围内的所需的被动用户频段，并拒绝活跃的用户作为Jammers。另一方面，将开发一个用于Active（移动）用户端资源分配的被动用户友好的协议。该协议将特别考虑被动用户端上提出的电气接收器的灵敏度和线性，以及非均质活动活性用户应用程序的潜水员功能和服务要求。该协议的在线算法具有可证明的服务保证。该奖项反映了NSF的法定任务，并认为使用基金会的知识分子优点和更广泛的影响审查标准，被认为值得通过评估。
