摘要： This Letter designed an extra high reflection filter by using multilayers with a negative k, commonly referred to as gain layers. The gain layer was fabricated by embedding CdS quantum dots in a dielectric layer. Experimental results indicated that the effective k value is around -0.0008. The associated optical and physical properties were also discussed. The application of gain layers is very forward-looking. 其他題名： Opt Lett 出版者： United States 出版日期： 2013-09-01 出處： Optics letters, 2013-09, Vol.38 (17), p.3377-3379 資源來源： Optica Publishing Group Journals 識別號： ISSN: 0146-9592 識別號： ISSN: 1539-4794 識別號： EISSN: 1539-4794 識別號： DOI: 10.1364/OL.38.003377 識別號： PMID: 23988962
