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，如射电天文学接收机，或大气和地球空间科学和气候观测接收机，对其他有源无线干扰，如地面蜂窝通信信号极其敏感。因此，它们通常需要专用射频频带以及围绕它们的保护频带沿着。在许多情况下，主动用户在这些地区可能实际上并不共存，因此在偏远地区建造了许多被动用户基础设施。这种情况通常会降低有效频谱效率，阻碍被动系统的部署，并对未来的科学发现造成障碍。一种新的方法是允许被动和主动用户在相邻频带和相邻位置工作。这将允许活跃用户在先前不允许的保护频带中操作，从而显著提高频谱效率。 该项目介绍了无源用户侧的芯片级微波硅光子（SiP）自适应滤波器架构和有源（移动的）用户侧的资源分配的无源用户友好协议的创新，从而解决了无源和有源（移动的）用户之间的有效频谱利用/共存。该项目中提出的关于微波SiP滤波器沿着无线协议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化。除了技术影响外，拟议项目还促进外联活动，以增加代表性不足群体的学生对科学和工程的参与，包括每年为高中生举办为期一周的夏令营。本项目的研究和教育成果将传播到学术界、工业界和政府部门。本项目旨在开发（1）无源用户侧的新型芯片级微波SiP可重构/自适应滤波器架构，使用由纳米互补金属氧化物半导体（CMOS）SOI控制的绝缘体上硅（SOI）光学芯片，芯片，其允许电控滤波器配置和干扰抑制以动态地保护被动用户的频带，以及（2）用于主动（移动的）用户侧上的资源分配的被动用户友好协议。本研究的目标是：（1） 微波SiP/CMOS自适应滤波器架构及其光子学/电子学组件，沿着用于它们在被动用户侧上的自动调谐的算法/硬件，（2）用于所提出的被动用户友好协议的具有可证明的服务保证的在线策略，以及（3）在被动用户和主动用户侧的资源分配协议上提出的自适应滤波器的混合集成，验证有效的频谱利用率。多功能微波SiP自适应滤波器单元将在主天线和低噪声放大器（在室温或低温下）之后潜在地连接到室温下的无源用户接收器。该单元包括高度选择性可重新配置的SiP带通和陷波滤波器，以动态选择10-50 GHz范围内的所需无源用户频带，并将有源用户作为干扰源拒之门外。另一方面，将开发用于主动（移动的）用户侧的资源分配的被动用户友好协议。该协议将特别考虑被动用户侧的电光接收器的灵敏度和线性度，以及异构主动用户应用的各种功能和服务要求。该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
