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

0642603智力价值：本项目的目标是研究和应用最近开发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）的参量过程和非线性辅助慢波传播将在全光波长转换、光缓冲和可调谐时延等应用中得到发展。这样做的好处是避免使用昂贵的高功率固态激光器、使用体光学器件的困难且对环境敏感的相位匹配布局以及长光纤。相反，这些器件有效地使用低光功率水平，与片上光源、调制器和新型波导元件兼容，这些元件可以设计色散和相位匹配条件。光学传感、计量和数据/图像处理器件将大大受益于低功率片上可编程线性/非线性滤波功能。芯片级非线性光子学将使先进的光网络功能由最终用户设备执行，而不仅仅是在网络核心。台式计算机、手持笔记本电脑和PDA，以及最终的蜂窝电话可能具有基于低功率、高效波长转换和光存储器技术的光学芯片组，这将使它们能够直接连接到光纤互联网。如果光缓存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加高效、通用、安全、具有成本效益和适应性。更广泛的影响：在过去的五年里，PI在耦合谐振器（作为快速发展的微谐振器领域的一个领域）的理论和实验方面发挥了主要作用。这个职业建议是PI在该领域的研究和教育方面的努力的基础。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设备的色散和非线性光学特性，从而增强UCSD光波导研究的基础设施。将为一门新的研究生课程“光学谐振器及其应用”编写教材。研究生和本科生的研究将得到支持，妇女在工程中的参与将继续发展，并为少数民族学生的推广计划将加强与加州少数民族参与联盟和普鲁斯学校在加州大学圣地亚哥分校的参与。

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.
