Abstract:	摘要： AbstractIn this work, we study the performances of ring resonators of different type by analyzing the bending loss and the condition of the critical coupling. We propose that the bending loss of microring can be reduced by wrapping a concentrically curved waveguide. The difference of propagation constant between two concentrically curved waveguides can be tuned by adjusting the bus waveguide width to optimize the critical coupling. Furthermore, we propose to enlarge the difference of the propagation constant between two concentrically curved waveguides to maintain the circulating light in the ring to obtain higher quality factor. In this study, the highest quality factor that we measured is 7 × 105. 其他題名： Sci Rep 出版者： London: Springer Science and Business Media LLC 出版日期： 2015-05-20 出處： Scientific Reports, 2015-05, Vol.5 (1), p.10078-, Article 10078 資源來源： Springer Nature link journals (open access titles) 版權： The Author(s) 2015 版權： Copyright Nature Publishing Group May 2015 版權： Copyright © 2015, Macmillan Publishers Limited 2015 Macmillan Publishers Limited 識別號： ISSN: 2045-2322 識別號： EISSN: 2045-2322 識別號： DOI: 10.1038/srep10078 識別號： PMID: 25993265
