Objective: The objective of this program is to expand the realm of silicon photonics into the mid-infrared wavelength range. The common silicon-on-insulator platform is not suited due to silica loss in the mid-infrared. Sapphire is transparent in this wavelength range, thus all the proposed devices will be fabricated on silicon-on-sapphire wafers. The expected outcomes are: (a) Passive coherent beam-combiners pumped by quantum cascade lasers; (b) Active coherent beam-combiners based on silicon Raman lasers; (c) Wavelength-tunable version of the active beam-combiner; and (d) Parametric optical amplifiers and continuum generation sources.Intellectual merits: The intellectual merit of this program is: (a) It will develop a novel mid-infrared photonics platform; (b) Instead of mechanically duplicating the existing near-infrared architectures, new photonic devices that carefully target the specific needs of mid-infrared integrated photonics are envisioned; (c) The proposed device architectures take into account the requirement of their monolithic integration on the same silicon chip; and (d) Rather than trying to compete with existing technologies on III-V compound semiconductors, silicon photonics will be employed as a complementary technology to advance the field of mid-infrared photonics. Broader impacts: The broader impacts are providing: (a) Photonics solutions with potential applications in environmental and biochemical sensors, biomedical equipment, free-space communications and homeland security and surveillance systems with direct impact on the daily life of our society; (b) Interdisciplinary research context for Ph.D. students; (c) Integrated outreach activities that span K-12 and college-level women and other underrepresented minorities in collaboration with local educational institutions.

目的：本计划的目标是将硅光子学的领域扩展到中红外波长范围。常见的绝缘体上硅平台由于在中红外中的二氧化硅损失而不适合。蓝宝石在这个波长范围内是透明的，因此所有提出的器件都将在蓝宝石上硅晶片上制造。预期成果是：（a）由量子级联激光器泵浦的无源相干合束器;（B）基于硅拉曼激光器的有源相干合束器;（c）波长可调的有源合束器;（d）参量光放大器和连续谱产生源。（B）不是机械地复制现有的近红外结构，而是设想了仔细地针对中红外集成光子学的具体需要的新的光子器件;以及（d）硅光子学将被用作推进中红外光子学领域的补充技术，而不是试图与III-V族化合物半导体的现有技术竞争。更广泛的影响：更广泛的影响是提供：（a）光子学解决方案，在环境和生物化学传感器，生物医学设备，自由空间通信和国土安全和监控系统的潜在应用，对我们社会的日常生活的直接影响;（B）跨学科的研究背景博士。学生;（c）与当地教育机构合作，开展涵盖K-12和大学一级妇女及其他代表性不足的少数群体的综合外联活动。
