中文摘要:一维光子准晶已在亚波长、亚衍射聚焦及超分辨成像领域不断展现优越性。为丰富及拓展其聚焦特性的应用,本文提出了一种一维光子准晶平V透镜,并研究了材料厚度对其聚焦特性的影响。研究结果表明,该透镜可在第二能带较宽的波长范围内实现亚波长及亚衍射聚焦。本文研究结果将为一维光子准晶平V透镜的设计及应用提供参考。

One-dimensional photonic quasi-crystal plano-V lens
Abstract:One-dimensional photonic quasi-crystal (1D PQC) has continuously shown their superiority in the fields of sub-wavelength focusing, sub-diffraction focusing and super-resolution imaging. In order to enrich and expand the application of its focusing characteristics, a 1D PQC plano-V lens is proposed and the effect of material thickness on its focusing characteristics is studied in this paper. The results show that the lens can achieve sub-wavelength focusing and sub-diffraction focusing in a wide wavelength range of the second band. The results in this paper will provide reference for the design and application of 1D PQC plano-V lens.
