Abstract

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.
