CAREER: Chip-scale low-power nonlinear optics using coupled resonators and CROWs

智能优点：本项目的目标是研究和应用最近发展起来的基于耦合谐振器和耦合谐振器光波导的光波导技术，用于低功率可调谐非线性光学。基于CHI(3)的参数过程和非线性辅助慢波传播将被开发用于全光波长转换、光学缓冲和可调时延等应用。这样做的好处是避免了使用昂贵的高功率固态激光器、使用块状光学器件的困难且对环境敏感的相位匹配布局以及较长长度的光纤。相反，这些设备高效地使用与片上光源、调制器和可调节色散和相位匹配条件的新型波导组件兼容的低光功率级别。光学传感、计量和数据/图像处理设备将从低功率片上可编程线性/非线性滤波功能中受益匪浅。芯片规模的非线性光子学将使高级光网络功能能够由最终用户设备执行，而不仅仅是在网络核心。台式计算机、手持笔记本和PDA，以及最终的蜂窝电话可能具有基于低功率、高效波长转换和光学存储技术的光学芯片组，这将使它们能够直接连接到光纤互联网。如果光缓冲和波长转换可以从核心路由器和网关中分离出来，而不会在复杂性或功耗方面付出高昂的代价，则可以使异类网络变得更加高效、通用、安全、成本效益和适应性更强。更广泛的影响：在过去的五年里，PI发挥了主要作用，发展了耦合谐振器(作为快速发展的微谐振器领域的一个领域)的几个理论和实验方面。这一职业建议对国际和平协会在这一领域的研究和教育方面的努力是至关重要的。这项工作将通过创建一种快速测量基于谐振器的器件的色散和非线性光学特性的新设备来增强加州大学圣迭戈分校的光波导研究基础设施。将为一门新颖的研究生课程“光学谐振器及其应用”准备教材。将支持研究生和本科生的研究，将继续发展女性参与工程学，并将在加州少数族裔参与联盟和加州大学圣迭戈分校普赖斯学校的参与下，加强针对少数族裔学生的外联计划。

0642603Intellectual merit: The goal of this project is to investigate and apply a recently-developed optical waveguiding technology based on coupled resonators and coupled-resonator optical waveguides for low-power tunable nonlinear optics. Chi-(3) based parametric processes and nonlinearly-assisted slow wave propagation will be developed for applications such as all-optical wavelength conversion, optical buffering and tunable time delay. The benefit is to avoid using expensive high-power solid-state lasers, difficult and environmentally-sensitive phase-matching layouts using bulk optics, and long lengths of optical fiber. Instead the devices efficiently use low optical power levels compatible with on-chip sources, modulators, and novel waveguide components which can engineer the dispersion and phase-matching conditions.Optical sensing, metrology and data/image processing devices will benefit substantially from low-power on-chip programmable linear/nonlinear filtering functionality. Chip-scale nonlinear photonics will enable advanced optical networking functionality to be performed by end-user devices rather than only at the network core. Desktop computers, handheld notebooks and PDAs, and eventually cellular phones may have optical chipsets based on low-power, highly-efficient wavelength conversion and optical memory technology which will enable them to connect directly to the fiber-optic internet. Heterogeneous networks can be made more efficient, versatile, secure, cost-effective and adaptable if optical buffering and wavelength conversion can be de-centralized from the core routers and gateways without paying a high penalty in complexity or power consumption. Broader impact: The PI has played a principal role developing several of the theoretical and experimental aspects of coupled-resonators (as an area of the rapidly developing field of micro-resonators) over the last five years. This CAREER proposal is fundamental to the PI's efforts on both the research and educational aspects of this field. The work will enhance the infrastructure for optical waveguide research at UCSD by creating a new facility for rapid measurement of dispersive and nonlinear optical properties of resonator-based devices. Instructional material for a novel graduate course "Optical Resonators and their Applications" will be prepared. Graduate and undergraduate student research will be supported, the participation of women in engineering will continue to be developed, and an outreach program for minority students will be enhanced with the involvement of the California Alliance for Minority Participation and the Preuss School at UCSD.
