0622212 Dr.该项目旨在通过发展先进的理论和计算技术，通过探索与时间反转对称破缺相关的新的光学效应，以及通过与实验者合作演示芯片上超紧凑的光子晶体隔离器，来极大地推动光子晶体系统中磁光技术的发展。从器件应用的角度来看，制造片上大规模集成光学器件最根本的挑战之一是提供信号隔离和抑制器件之间的寄生反射。在这种背景下，人们对非互易光学器件的小型化及其芯片上集成产生了非常浓厚的兴趣。在此背景下，本项目将极大地有助于创造具有增强功能的单波长规模的超紧凑型设备的努力。广泛影响：该项目为研究生提供了极好的培训机会。此外，作为外展和教育努力的一部分，将积极招募少数族裔研究生参与这一项目，并从斯坦福大学的工程多样性计划获得额外资金。还特别注重将本科生纳入研究计划，以及与专业人士和当地社区的接触。

0622212Dr. Shanhui Fan, Stanford UniversityIntellectual Merits: This project seeks to greatly advance the state-of-the-art of magneto-optics in photonic crystal systems by developing advanced theoretical and computational techniques, by exploring new optical effects related to time-reversal symmetry breaking, and by collaborating with experimentalist towards the demonstration of on-chip ultra-compact photonic crystal isolators. From a device application point of view, one of the most fundamental challenges to create on-chip large-scale integrated optics has been to provide signal isolation and to suppress parasitic reflections between devices. In this context, there is a very strong interest in the miniaturization of non-reciprocal optical devices and their on-chip integration. In this context, the present project will greatly benefit the efforts of creating ultra-compact devices at a single-wavelength scale with enhanced functionalities.Broader impacts: This project provides excellent training opportunities for graduate students. In addition, as part of the efforts on outreach and education, minority graduate students will be actively recruited to work on this project with additional fund secured from Stanford University's Engineering Diversity Program. Special focus is also placed on incorporating undergraduate students into the research program, as well as on outreach to the professional and local communities.
