Vision is one of our more important senses. In many situations, humans develop and apply technologies to enable them to “see” better or to expand the range of wavelengths over which the human eyes are sensitive for many demanding applications in health and environmental sciences. The proposed work is part of our ongoing research program in advanced optical detectors and imaging systems. Here, we propose to use two technologies, each with distinct advantages for the targeted applications. One technology uses quantum dot infrared photodetectors for mid-infrared medical and environmental sensing applications. Another technology uses low-cost, silicon-based photodetectors and high-performance integrated circuits to create imagers with world-class performance for biomedical imaging applications. The proposed research leverages our 2.5 decades of expertise and experience in photodetector design and integrated circuits to create fully integrated silicon-based and hybrid compound semiconductor-based optical detection systems for low-cost, miniaturized biomedical and environmental sensing and imaging systems. Our focus will be on the following. - Modeling and optimized design of “foundry-based” low-cost, high-performance optical detectors, pixels, digital integrated circuits and integrated imagers for applications including early disease detection using positron emission tomography, functional brain imaging or fluorescent lifetime imaging. - Mitigation of challenging issues that degrade the performance of advanced photodetectors and imagers such as noise, afterpulsing, jitter or timing resolution. - Accurate, calibrated models to predict the static and dynamic characteristics of advanced quantum dot infrared photodetector structures, and their optimized design and fabrication for mid-infrared biological and chemical sensing applications. The novelty and impact of the proposed research include the modeling and optimized design of high-performance silicon photodetectors and imagers with tailored performance characteristics that can be successfully manufactured at first attempt, thus saving both time and money; and computationally efficient, accurate modeling and manufacture of quantum-based photodetectors. The research is highly significant because it targets high-impact, emerging national needs in health sciences, especially the screening and early detection of costly diseases such as cancers. Finally, it would also help to maintain our leadership position in advanced photodetectors and imagers.

视觉是我们更重要的感官之一，人类开发和应用技术使他们能够更好地“看到”或扩大人眼敏感的波长范围，以适应健康和环境科学中许多要求较高的应用。拟议的工作是我们正在进行的先进光学探测器和成像系统研究计划的一部分，在这里，我们建议使用两种技术，每种技术对于目标应用都有独特的优势。 一项技术使用量子点红外光电探测器用于中红外医疗和环境传感应用，另一种技术使用低成本硅基光电探测器和高性能集成电路来创建用于生物医学成像应用的具有世界一流性能的成像器。利用我们在光电探测器设计和集成电路方面 2.5 年的专业知识和经验，为低成本、小型化生物医学和环境传感和成像系统创建完全集成的基于硅和混合化合物半导体的光学检测系统。重点将放在以下方面。 - 对“基于代工厂”的低成本、高性能光学探测器、像素、数字集成电路和集成成像器进行建模和优化设计，其应用包括使用正电子发射断层扫描、功能性脑成像或荧光寿命成像进行早期疾病检测。 - 缓解降低先进光电探测器和成像仪性能的挑战性问题，例如噪声、后脉冲、抖动或定时分辨率。 - 准确、校准的模型，用于预测先进量子点红外光电探测器结构的静态和动态特性，及其针对中红外生物和化学传感应用的优化设计和制造。 所提出的研究的新颖性和影响包括高性能硅光电探测器和成像器的建模和优化设计，这些光电探测器和成像器具有定制的性能特征，可以在第一次尝试时成功制造，从而节省时间和金钱，以及计算效率高、精确的建模和制造；这项研究非常重要，因为它针对的是健康科学领域的高影响力、新兴的国家需求，特别是癌症等昂贵疾病的筛查和早期检测，最后，它也将有助于保持我们在该领域的领导地位。先进的光电探测器和成像仪。
