NIRT: Optical Interconnects for High-Performance Processors: Architectures, Circuits, and DevicesAbstractThis proposal was received in response to Nanoscale Science and Engineering initiative, NSF 02-148, category NIRT. This project involves the development of nanoscale-silicon-based optical interconnect technology and associated design methodologies to alleviate the global signaling problem in future CMOS chips. The device research focuses on two specific building blocks, namely a silicon laser and silicon modulators/switches. The laser is made using silicon quantum dots as the gain medium. Both optically pumped and electrically pumped laser structures are being investigated. The modulators/switches are made of tunable photonic bandgap structures made of silicon infiltrated with an electrically active material such as liquid crystals. In addition, optimal signaling at both the data and control levels is being explored, and solutions developed, while taking into consideration both the structural characteristics of the system architecture and the impedance and physical constraints of the electrical/optical interface. In the process, an integrated modeling environment spanning the nanoscale device, integrated circuit, and architecture levels is being created in order to conduct this research. Top-down and bottom-up design methodologies are being developed for potential incorporation into commercial design automation tools.Several educational initiatives are intricately linked with this research (including undergraduate design projects, summer employment of undergraduates, graduate student research, participation in diversity programs, and tutorials given at leading conferences and forums) in order to educate current and future applied physicists, electrical engineers, and computer scientists in the broad aspects of this interdisciplinary field.

NIRT：高性能处理器的光互连：体系结构、电路和器件摘要本提案是响应NSF 02-148，类别NIRT的纳米级科学和工程倡议而收到的。 该项目涉及基于纳米硅的光学互连技术和相关设计方法的开发，以减轻未来CMOS芯片中的全球信号问题。 器件研究集中在两个特定的构建模块，即硅激光器和硅调制器/开关。 激光器是用硅量子点作为增益介质制成的。 光泵浦和电泵浦激光器结构都在研究之中。 调制器/开关由可调光子带隙结构制成，该可调光子带隙结构由渗透有诸如液晶的电活性材料的硅制成。 此外，正在探索数据和控制级别的最佳信令，并开发解决方案，同时考虑系统架构的结构特征以及电/光接口的阻抗和物理约束。 在这个过程中，一个集成的建模环境，跨越纳米器件，集成电路和架构水平正在创建，以进行这项研究。 自上而下和自下而上的设计方法正在开发中，有可能被纳入商业设计自动化工具。（包括本科生设计项目，本科生暑期就业，研究生研究，参与多样性计划，以及在领先的会议和论坛上提供的教程），以教育当前和未来的应用物理学家，电气工程师，和计算机科学家在这个跨学科领域的广泛方面。
