As an important application of such HLPGs, the orbital angular momentum (OAM) mode converters enabling to have either a flat-top bandwidth of ~116 nm@-16 dB but centered at wavelength of ~1530 nm, or a flat-top bandwidth ~130 nm @-16 dB but centered at wavelength of ~1650 nm, have been successfully demonstrated. This is the first report for the experimental demonstration of such high-performance band-rejection filters with bands fully matching the C-L bands of the fiber communication.

The structure consists of a symmetric-protected BIC metal structure layer, a polyimide spacer layer, and a silicon substrate. The top layer contains two similar metal structures, which make the structure asymmetric by varying one of them slightly, thus producing a symmetrical broken quasi-BIC. When a metal reflecting plate is added to the bottom of the dielectric spacer layer, a quasi-BIC absorber is formed. This is the first theoretical calculation using the coupled mode equation to analyze the relationship between the absorption frequency of a quasi-BIC absorber and the quasi-BIC resonance frequency, which is related to the resonance frequency of a single structure in a unit cell. According to the relationship between the coupling strength and distance between the structures within a unit cell combined with the resonant frequency of quasi-BIC, the geometric parameters of the absorber within a frequency range can be inverse design.","PeriodicalId":13200,"journal":{"name":"IEEE Journal of Quantum Electronics","volume":"60 3","pages":"1-11"},"PeriodicalIF":2.5,"publicationDate":"2024-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140820418","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
