The analysis indicates the experimentally obtained miscellaneous peaks are mainly induced by the multiple reflections between the two end grating couplers, which form a F-P cavity. In addition, an anti-reflection film on the interface of the grating couplers is proposed to reduce the F-P resonance effect. This work could be useful to analyze optical transmission properties of other MRR-based structures.<\/jats:p>","DOI":"10.3390\/s21196370","type":"journal-article","created":{"date-parts":[[2021,9,27]],"date-time":"2021-09-27T22:16:38Z","timestamp":1632780998000},"page":"6370","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Optical Transmission Properties of Si3N4 Add-Drop Micro-Ring Resonator Induced by a Fabry\u2013Perot Resonance Effect"],"prefix":"10.3390","volume":"21","author":[{"given":"Xinyang","family":"Chen","sequence":"first","affiliation":[{"name":"The Key Laboratory of Optoelectronic Technology & System, Education Ministry of China, Chongqing University, Chongqing 400044, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Linpeng","family":"Gu","sequence":"additional","affiliation":[{"name":"Key Laboratory of Light-Field Manipulation and Information Acquisition, Ministry of Industry and Information Technology, Xi\u2019an 710129, China"},{"name":"Shaanxi Key Laboratory of Optical Information Technology, School of Science, Northwestern Polytechnical University, Xi\u2019an 710129, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Peijian","family":"Huang","sequence":"additional","affiliation":[{"name":"The Key Laboratory of Optoelectronic Technology & System, Education Ministry of China, Chongqing University, Chongqing 400044, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xuetao","family":"Gan","sequence":"additional","affiliation":[{"name":"Key Laboratory of Light-Field Manipulation and Information Acquisition, Ministry of Industry and Information Technology, Xi\u2019an 710129, China"},{"name":"Shaanxi Key Laboratory of Optical Information Technology, School of Science, Northwestern Polytechnical University, Xi\u2019an 710129, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ning","family":"Wang","sequence":"additional","affiliation":[{"name":"The Key Laboratory of Optoelectronic Technology & System, Education Ministry of China, Chongqing University, Chongqing 400044, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yong","family":"Zhu","sequence":"additional","affiliation":[{"name":"The Key Laboratory of Optoelectronic Technology & System, Education Ministry of China, Chongqing University, Chongqing 400044, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jie","family":"Zhang","sequence":"additional","affiliation":[{"name":"The Key Laboratory of Optoelectronic Technology & System, Education Ministry of China, Chongqing University, Chongqing 400044, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2021,9,24]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"407","DOI":"10.1038\/nphoton.2007.93","article-title":"Electro-optically tunable microring resonators in lithium niobate","volume":"1","author":"Guarino","year":"2007","journal-title":"Nat.
