摘要

本文提出了一种用于片上光互连的串行耦合至7阶的高阶微环谐振器滤波器。这项工作主要集中在实现平顶，更高的带外抑制比，和增强的群延迟值比先前演示的微环滤波器。在此基础上，利用连分数法研究了不同腔间耦合系数对1552 nm波长滤波运算的影响，实现了环-环波导间耦合系数的优化条件，从而获得陡峭的边缘响应。所提出的设计在耦合值为0.04时显示出7.457 ps的最小群延迟。

High order coupled microring resonator filters for on-chip optical interconnects with steep edge response

ABSTRACT In this paper, high-order microring resonator filters coupled serially up to the 7th order are proposed for on-chip optical interconnects. This work mainly focuses on achieving a flat-top, higher out-of-band rejection ratio, and enhanced group delay value than previously demonstrated microring filters. Further, the effect of varying inter-resonator coupling coefficients on the filtering operation of wavelength 1552 nm is investigated, using the continued fraction method, and optimum conditions for coupling coefficients between ring-ring waveguides are realized to obtain steep edge response. The proposed design exhibits a minimum group delay of 7.457 ps at a coupling value of 0.04.

期刊介绍： Fiber and Integrated Optics , now incorporating the International Journal of Optoelectronics, is an international bimonthly journal that disseminates significant developments and in-depth surveys in the fields of fiber and integrated optics. The journal is unique in bridging the major disciplines relevant to optical fibers and electro-optical devices. This results in a balanced presentation of basic research, systems applications, and economics. For more than a decade, Fiber and Integrated Optics has been a valuable forum for scientists, engineers, manufacturers, and the business community to exchange and discuss techno-economic advances in the field.
