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.

智力优势：本课题的目标是研究和应用一种基于耦合谐振器和耦合谐振器光波导的新发展的光波导技术，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用于全光波长转换、光缓冲和可调时间延迟等应用。其优点是避免使用昂贵的高功率固态激光器，使用大块光学器件的相位匹配布局困难且对环境敏感，以及长长度的光纤。相反，该器件有效地使用与片上光源、调制器和新型波导元件兼容的低光功率电平，从而可以设计色散和相位匹配条件。光学传感、计量和数据/图像处理设备将从低功耗片上可编程线性/非线性滤波功能中受益匪浅。芯片级非线性光子学将使先进的光网络功能能够由终端用户设备执行，而不仅仅是在网络核心。台式电脑、掌上笔记本和pda，以及最终的移动电话都可能拥有基于低功耗、高效波长转换和光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散出来，而不会在复杂性或功耗方面付出高昂的代价，那么异构网络可以变得更高效、更通用、更安全、更具成本效益和适应性。更广泛的影响：在过去的五年中，PI在耦合谐振器（作为微谐振器快速发展领域的一个领域）的几个理论和实验方面发挥了主要作用。这一职业建议对PI在该领域的研究和教育方面的努力至关重要。这项工作将通过创建一个新的设备来快速测量基于谐振器的器件的色散和非线性光学特性，从而增强加州大学圣地亚哥分校光波导研究的基础设施。为一门新的研究生课程“光谐振器及其应用”准备教学材料。研究生和本科生的研究将得到支持，女性在工程领域的参与将继续得到发展，在加州少数民族参与联盟和加州大学圣地亚哥分校普鲁斯学院的参与下，少数民族学生的外展计划将得到加强。
