Abstract
Two-dimensional arrays of nanoscale metalens can allow scaling down of bulky optical components into planar device structures. Capasso et al. [1] achieved visible wavelength metalens by using nanoscale fin arrays of dielectric material TiO2, to be able to reach diffraction-limited focal points at design wavelengths, making them ideal for optical applications. Zinc monoxide (ZnO) nanopillars are used to modulate the phase of the light on the metalens due to its transparent property for visible light [2]. In this study, the trifocal metalens, which is composed of the nanopillars array structure of dielectric materials, is designed and simulated by finite-difference time-domain (FDTD) method. The optical properties of designed metalens will be also discussed.
