By optimizing etching depth, the proposed coupler can perform similarly for both polarizations in broadband. According to simulation results, the minimum difference between the TE and TM coupling coefficients can be kept less than 1% in 100 nm of the wavelength range.","PeriodicalId":131383,"journal":{"name":"2020 Italian Conference on Optics and Photonics (ICOP)","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133886579","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
