广义Fibonacci波带片

Generalized Fibonacci zone plates

Jie Ke, Junyong Zhang, Jianqiang Zhu

摘要:

提出了一类由广义Fibonacci序列产生的波带片,并详细分析了它们的轴向聚焦特性。与传统的菲涅耳波带片相比,广义Fibonacci波带片呈现出两个轴向光强相等的焦点。此外,还提出了利用不同光程差调整两焦点轴向位置的方法,并进一步给出了两焦点的确定性比值,该比值对应于它们各自的广义Fibonacci序列。广义斐波那契波带片可以允许在微米和纳米光子学中的新应用。

英文摘要:

We propose a family of zone plates which are produced by the generalized Fibonacci sequences and their axial focusing properties are analyzed in detail. Compared with traditional Fresnel zone plates, the generalized Fibonacci zone plates present two axial foci with equal intensity. Besides, we propose an approach to adjust the axial locations of the two foci by means of different optical path difference, and further give the deterministic ratio of the two focal distances which attributes to their own generalized Fibonacci sequences. The generalized Fibonacci zone plates may allow for new applications in micro and nanophotonics.
