Theory of Non-Reciprocal Photonic Crystals

0622212博士Shanhui Fan，斯坦福大学智力优势：该项目旨在通过发展先进的理论和计算技术，通过探索与时间反演对称性破缺相关的新光学效应，以及与实验学家合作演示片上超紧凑光子晶体隔离器，极大地推进光子晶体系统中磁光学的最新技术水平。从器件应用的角度来看，创建片上大规模集成光学器件的最基本挑战之一是提供信号隔离并抑制器件之间的寄生反射。在这种情况下，有一个非常强烈的兴趣，在非互易光学器件的小型化和它们的片上集成。在这种情况下，本项目将大大有利于在单波长尺度上创建具有增强功能的超紧凑器件的努力。更广泛的影响：本项目为研究生提供了极好的培训机会。此外，作为推广和教育工作的一部分，将积极招募少数民族研究生参与这一项目，并从斯坦福大学工程多样性方案获得额外资金。还特别注重将本科生纳入研究计划，以及对专业和当地社区的推广。

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.
