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.

摘要

这封信通过使用具有负 k 值（通常称为增益层）的多层设计了一个超高反射滤波器。增益层是通过在介电层中嵌入 CdS 量子点来制造的。实验结果表明，有效 k 值约为-0.0008。还讨论了相关的光学和物理性质。增益层的应用非常有前瞻性。
