Optical spectroscopy excels at chemical identification and is ubiquitous in the sciences as a highly specific and noninvasive probe of molecular structure. Moving forward the integration of miniaturized optical spectrometers into mobile platforms will have unprecedented impact on applications ranging from unmanned aerial vehicles to mobile phones. To address this demand, silicon photonics stands out as a manufacturable platform capable of delivering compact and cost-effective devices and systems. Its implementation in silicon photonics manufacturing will contribute to bringing broadband operation and fine resolution to the chip scale enabling such attributes as compactness, power efficiency, real time operation and low cost. Thus integrated spectrometers will have a profound impact by incorporation into various mobile platforms and creation of distributed sensor networks towards large scale internet of things applications. The proposed research will advance the basic science and technology of engineered CMOS manufactured Si-Photonic integrated systems on a chip. We anticipate that the spectrometer will find applications in monitoring environment, healthcare, national security, and defense applications. The project will provide scientific training for students at graduate and undergraduate levels as well as serve as a platform for outreach, education and collaborative efforts with middle and high schools. Significant efforts have been directed towards the realization of miniaturized, embedded optical spectrometers for spectral analysis in numerous areas of science and technology including remote sensing, planetary sciences, medical research, and pharmaceutical processes. The state of the art Optical Fourier Transform spectroscopy has thus far been relegated as a benchtop instrument owing to the large footprint and mechanical stability necessary for accurate operation. To overcome this limitation, we propose to develop an integrated chip-scale Fourier transform spectrometer that is fully CMOS compatible. This approach will improve the measurement speed, and relax the sampling rate and dynamic range requirements compared to conventional ones, and retain the strong advantages that Fourier transform spectrometers possess compared to other conventional designs, such as superior performance in power throughput, operation in noisy environments, and accuracy. To reach these goals, we propose to achieve the following objectives: (1) design a chip-scale spectrometer on a chip (2) fabricate it as a monolithic integrated device, (3) experimentally test and characterize the performance of the constructed device and (4) devise signal processing algorithms for concatenation of the detected channelized signals to construct high resolution broad band resultant spectra. Rapid prototyping and testing will be performed at UCSD with full scale runs performed at the AIM Photonics foundry. The proposed research is transformative in nature as it will not only mark the first step toward integration of inexpensive, compact, high resolution sensitive spectrometers into mobile phone technology, but also offer a route to ultra-compact networked sensor systems for environmental management, medicine, and security. The project will provide scientific training for students at graduate and undergraduate levels as well as serve as a basis for outreach, education and collaborative efforts with middle and high schools. Engagement of students of diverse ethnicity, gender and economic backgrounds in Science, Technology, Engineering and Mathematics (STEM) will be continued via the ongoing RET, REU, and COSMOS activities.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.

光学光谱学擅长于化学鉴定，作为一种高度特异的、非侵入性的分子结构探针，在科学界无处不在。展望未来，将微型光学光谱仪集成到移动平台中将对从无人机到手机的各种应用产生前所未有的影响。为了满足这一需求，硅光电子作为一种可制造的平台脱颖而出，能够提供紧凑且具有成本效益的设备和系统。它在硅光电子制造中的实施将有助于将宽带操作和精细分辨率带入芯片规模，从而实现紧凑性、功率效率、实时操作和低成本等属性。因此，集成光谱仪将对各种移动平台和分布式传感器网络的大规模物联网应用产生深远的影响。本文的研究成果将对工程制造的硅-光子集成系统的基础科学和技术发展起到推动作用。我们预计，该光谱仪将在环境监测、医疗保健、国家安全和国防应用中得到应用。该项目将为研究生和本科生提供科学培训，并作为与初中和高中进行外联、教育和合作的平台。在许多科学和技术领域，包括遥感、行星科学、医学研究和制药过程中，为实现用于光谱分析的微型嵌入式光学光谱仪作出了重大努力。到目前为止，最先进的光学傅里叶变换光谱仪一直被归类为台式仪器，因为它占用空间大，而且机械稳定性是精确操作所必需的。为了克服这一局限性，我们建议开发一种完全兼容CMOS的集成芯片级傅里叶变换光谱仪。这种方法将提高测量速度，放宽对采样率和动态范围的要求，并保留了傅里叶变换光谱仪与其他传统设计相比的强大优势，如在功率吞吐量、在噪声环境中工作和精度方面的优越性能。为了实现这些目标，我们提出了以下目标：(1)设计芯片规模的片上光谱仪；(2)将其制作成单片集成器件；(3)实验测试和表征所构建的器件的性能；(4)设计信号处理算法，将检测到的信道化信号进行级联，以构建高分辨率的宽带合成光谱。将在加州大学圣迭戈分校进行快速原型制作和测试，并在AIM Photonics铸造厂进行全尺寸运行。这项拟议的研究具有变革性，因为它不仅标志着将廉价、紧凑、高分辨率的灵敏光谱仪集成到移动电话技术中的第一步，而且还为环境管理、医学和安全提供了一条超紧凑型网络传感器系统的途径。该项目将为研究生和本科生提供科学培训，并作为推广、教育和与初中和高中合作的基础。通过正在进行的RET、REU和COSMOS活动，将继续让不同种族、性别和经济背景的学生参与科学、技术、工程和数学(STEM)。该奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。
