However, the weak fluorescence of single rare-earth ions presents a significant challenge for scalability, necessitating the integration into microcavities. Thin films serve as a promising material platform for the integration, yet fabrication without compromising the properties of the materials and rare-earth ions remains challenging. In this work, we fabricate micrometer-thin yttrium aluminum garnet (YAG) films from bulk crystals using ion implantation techniques. The resulting films preserve the single-crystalline structure of the original bulk crystal. Notably, the embedded rare-earth ions are photostable and exhibit bulk-like spin coherence properties. Our results demonstrate the compatibility of bulk-like spin properties with the thin-film fabrication technique, facilitating the efficient integration of rare-earth ions into on-chip photonic devices and advancing the applications of rare-earth ionsin quantum technologies.","PeriodicalId":23,"journal":{"name":"ACS Photonics","volume":"2 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2025-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143507200","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

At the critical coupling conditions, narrow band perfect absorption is achieved even if the extinction coefficient of Si nanodisks is very small. We produce the designed structure by nanosphere lithography and studied the reflectance and photocurrent spectra as a function of the distance between a Si nanodisk array and a Au mirror.
