The COVID pandemic of 2020 demonstrated the worldwide need for low-cost, highly sensitive, rapiddiagnostic testing of diverse pathogens. While silicon photonics enables such a highly multiplexed label-freesensing capability with extremely high sensitivities, a handheld low-cost silicon nanophotonic sensoris still missing. Fabrication imperfections have made photonic sensor implementations difficult with a fixedwavelength laser and a single detector. Photonic measurement variabilities also arise from bindinguncertainties in nanophotonic pillars and trenches. The fundamental work in this proposal employs a novelon-chip dual polarization interferometry technique that will reduce photonic measurement variability, andnovel circuit implementations to enable electrically driven and electrically readout low-cost on-chipnanophotonic sensors. The working principle of the device, and circuit implementations of the device toovercome fabrication and measurement limitations have not been previously demonstrated. The state-of-the-art photonic device fabrication capabilities at a 300 mm CMOS foundry, namely AIM Photonics, withmonolithically integrated passive and active electrically biased photonic components will be employed inthis project. The project will involve students in optics, engineering, materials science, and physics fromthe University of Dayton and the University of North Texas who will not only learn about cutting-edgeSTEM (science, technology, engineering, and mathematics) research but also in computer aided designlayouts for foundry fabrication of next-generation co-integrated electronic-photonic devices. The projectwill also work with students and faculty in microbiology from the Dayton Early College Academy, andother middle and high school students in the greater Dayton, OH and Denton, TX areas. The handheldsensors will find applications in various domains of biological sensing for cancer diagnostics, infectiousdisease and opioid diagnostics, and environmental pollution monitoring as also in new drug discovery.The technical goals of this project will (a) demonstrate the principle of slow light enhanced interferometryon-chip; (b) investigate novel thin-film electro-optic phase shifters on silicon chip; (c) demonstrate on-chipreal time dual polarization interferometry; and (d) demonstrate an unprecedented fabrication tolerant siliconnanophotonic sensor operating in a compact package with electrical drive and electrical readout. Theprogram will expose students to interdisciplinary research encompassing lithography, photonics, electricalengineering, physics, biochemistry, and materials science. The project will culminate with the developmentof a USB-powered handheld optical biosensor kit. Project members will engage in science and technologyoutreach targeting middle and high school students in greater Dayton, OH and greater Denton, TX counties.Project activities will outreach to broaden the participation of minority students in STEM education andtraining. Students will be exposed to an innovation ecosystem with hands-on science and technologyexperience. Finally, the project will help to address the significant current need to build US-basedmanpower in the design and manufacturing of semiconductor chips.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.

2020年的共同大流行表明，全球对多种病原体的低成本，高度敏感，快速诊断的测试的需求。尽管硅光子学使具有极高敏感性的高度多重标记效能能力，但手持式低成本硅纳米含量仍然缺失。固定波长激光器和单个检测器的制造缺陷使光子传感器实现变得困难。光子测量变化也来自纳米光支柱和沟渠中的结合定义。该提案中的基本工作采用了NognOn-Chip双极化干涉仪技术，该技术将降低光子测量变异性，和Novel电路的实现，以实现电动驱动和电气读数低成本的芯片上频线传感器。以前尚未证明该设备的工作原理以及设备的电路制造和测量限制的电路实现。在300毫米CMOS铸造厂（即AIM光子学）中，最先进的光子设备制造能力将在此项目中使用单光集成的被动和主动的电偏光组件。该项目将涉及代顿大学和北德克萨斯大学的光学，工程，材料科学和物理学的学生，他们不仅将了解过饰面的Edgestem（科学，技术，工程和数学）研究，还将了解用于下一代共同构造的计算机辅助设计layouts。该项目将与代顿早期学院的学生和微生物学的学生和教职员工一起工作，俄亥俄州大代顿和德克萨斯州丹顿市的其他中学生。手持式传感器将在生物传感的各个领域中找到用于癌症诊断，感染性疾病和阿片类药物诊断和环境污染监测的应用。 （b）研究硅芯片上新型的薄膜电滤波相变； （c）证明丝束上双极化干涉仪； （d）展示了一种前所未有的制造耐受的硅发光传感器，在带有电气驱动器和电气读数的紧凑型包装中运行。该程序将使学生接受跨学科研究，包括光刻，光子学，电气化，物理，生物化学和材料科学。该项目将随着USB驱动的手持式光学生物传感器套件的开发而达到高潮。项目成员将参与科学和技术界的针对俄亥俄州大代顿市和德克萨斯州大丹顿市的中学生的科学和技术。学生将通过动手科学和技术经验接触创新的生态系统。最后，该项目将有助于满足当前在半导体芯片设计和制造中建立美国曼力的巨大需求。该奖项反映了NSF的法定任务，并被认为是值得通过基金会的知识分子和更广泛影响的评估评估标准来通过评估来支持的。
