WGM谐振器的多通道分/插滤波特性研究，由于对实现高性能的片上光互连、光互连处理器，甚至是光互连超级计算机的潜在意义，因而成为国际光子学领域的重要研究热点。然而，一个限制性能提升的基本矛盾，即提升Q值（或精细度F）与降低谐振器个数M之间的矛盾，一直未获得解决。为解决这一矛盾，本项目针对利用多模WGM谐振器中多重类EIT效应实现高Q（F）值多通道分/插滤波特性的科学问题，研究低M多模WGM谐振器结构中高Q（F）值类EIT效应、多重类EIT效应、多通道分/插滤波特性的实现方案、演化规律、产生机理、设计原则与方法。本项目不仅能够为基于多模WGM谐振器的类EIT效应、多重类EIT效应、多通道分/插滤波特性研究奠定理论基础，还能为高Q（F）值低M的片上多通道波分复用器提供技术原型，对于推动大容量、高集成度、低功耗的片上光互连的研究发展有着极为重要的理论意义。

Owing to the potential implications for high-performance on-chip optical interconnection, microprocessors using optical interconnection, and even supercomputers using optical interconnection, the WGM resonator based multi-channel add/drop filtering characteristics have been attracting more and more research interest in the field of integrated photonics. Nevertheless, there is always a fundamental tradeoff between the Q factor (the fineness F) and the resonator number M without solution, limiting the performance improvement of the filtering characteristics. To overcome the tradeoff, this project will focus on the scientific problems on the high Q (F) multi-channel add/drop filtering characteristics based on multiple EIT-like effect in multimode WGM resonators. In multimode WGM resonator configurations with low M, the scheme, the evolution, the generation mechanism, and the design rule will be studied for high Q (F) EIT-like effect, multiple EIT-like effect, and multi-channel add/drop filtering characteristics, respectively. The project not only can lay the foundation for the research on multimode WGM resonator based EIT-like effect, multiple EIT-like effect, and multi-channel add/drop filtering characteristics, but also can provide prototypes for on-chip wavelength division (de)multiplexers with high Q (F) and low M, being of theoretical significance for research and development of large-capacity and highly integrated on-chip optical interconnect with low power consumption.
