Focusing enhanced broadband metalens via height op-timization
文献摘要:
Metalenses are two-dimensional planar metamaterial lenses,which have the advantages of high efficiency and easy integration.Based on the method of spatial multiplexing,a metalens with a wide working waveband is designed by ar-ranging TiO2 nanopillars under the resonance phase regulation.In addition,choosing an assistant metalens with opti-mized heights is effective to enhance metalens's focusing,which is also illustrated in this paper.The metalens,de-signed with numerical aperture(NA)of 0.72 and center working wavelength of 600 nm,achieves the working wave-band of 550-660 nm,the focus point's size of below 420 nm,and the focusing efficiency of more than 30%.
