The proposed research is in the area of integrated photonic devices, with focus on advanced applications of coupled microring resonators (CMRs) for optical communication and optical interconnect systems. Microring resonators are travelling-wave optical resonators which have become a key building block in many photonic integrated circuits, thanks to their compact sizes, versatility, and ease of fabrication and integration. One of the most important applications of microring resonators is the construction of high-order optical filters by coupling multiple resonators together. Conventional microring filters are based on the one-dimensional (1D) coupling topology, which can only realize a limited set of spectral responses. By extending the coupling topology to two dimensions (2D), much richer spectral characteristics can be synthesized for advanced applications in optical spectral engineering, such as high-performance filters and dispersion compensators.*** The objective of the research is to investigate and explore novel applications of a new type of 2D CMR networks, namely those with complex field coupling coefficients. In these devices power exchange between adjacent resonators takes place via both the magnitude and phase of the electromagnetic fields, giving rise to novel effects not present in conventional CMRs with real coupling coefficients. The research aims to develop theory and techniques for designing and realizing general 2D CMR networks with complex field couplings. Novel applications such as bandpass filters with built-in dispersion compensation for Wavelength Division Multiplexing (WDM) communication systems, and the emerging class of fabrication-tolerant topologically-protected photonic devices will be proposed and experimentally demonstrated in the silicon material. The latter devices are based on the concept of 2D topological insulators in electronic systems, with unique properties such as robustness against structural disorder making these devices highly tolerant to fabrication imperfections.*** In addition to advancements in the field of microring resonators, the research is also expected to contribute to the development of silicon integrated photonics technology. Silicon photonics is rapidly becoming the industry standard for manufacturing photonic integrated circuits, driven by the growing demand for low-cost and large-scale integrated optics components for WDM and optical interconnect applications. The proposed research provides excellent opportunities for training highly-qualified personnel (HQP) in both the theoretical and technological development of silicon photonics. It is expected that the expertise gained, intellectual property developed and HQP trained through the research program will help accelerate the development of silicon photonics industry in Canada, as well as the broader optics and telecommunication industries.**

拟议的研究属于集成光子器件领域，重点关注耦合微环谐振器（CMR）在光通信和光互连系统中的高级应用。 微环谐振器是行波光学谐振器，由于其紧凑的尺寸、多功能性以及易于制造和集成，已成为许多光子集成电路的关键构建模块。 微环谐振器最重要的应用之一是通过将多个谐振器耦合在一起来构造高阶光学滤波器。 传统的微环滤波器基于一维 (1D) 耦合拓扑，只能实现有限的光谱响应集。 通过将耦合拓扑扩展到二维 (2D)，可以为光谱工程中的高级应用合成更丰富的光谱特性，例如高性能滤波器和色散补偿器。*** 本研究的目的是研究和探索新型 2D CMR 网络（即具有复杂场耦合系数的网络）的新颖应用。 在这些设备中，相邻谐振器之间的功率交换通过电磁场的幅度和相位进行，从而产生具有实际耦合系数的传统 CMR 中不存在的新颖效应。 该研究旨在开发设计和实现具有复杂场耦合的通用二维 CMR 网络的理论和技术。 诸如用于波分复用（WDM）通信系统的内置色散补偿的带通滤波器以及新兴的可制造拓扑保护光子器件等新颖应用将在硅材料中提出并进行实验演示。后者的器件基于电子系统中的二维拓扑绝缘体的概念，具有独特的特性，例如对结构无序的鲁棒性，使这些器件对制造缺陷具有高度的容忍度。*** 除了微环谐振器领域的进步外，该研究还有望为硅集成光子技术的发展做出贡献。 由于 WDM 和光互连应用对低成本和大规模集成光学元件的需求不断增长，硅光子学正在迅速成为制造光子集成电路的行业标准。 该研究为硅光子学理论和技术发展方面的高素质人才（HQP）培训提供了极好的机会。 预计通过该研究项目获得的专业知识、开发的知识产权和培训的 HQP 将有助于加速加拿大硅光子行业以及更广泛的光学和电信行业的发展。 **
