Abstract
In this paper, we present a novel photolithographic technique to achieve variable 1D or 2D nanostructural patterns using a fixed 2-D metallic phase mask based on surface plasmonic interference. With different polarizing orientations of the incident light and a diffraction-limited phase mask which is formed by a metallic square array with a large period, surface plasmons (SPs) interferometric parttens with resolutions beyond diffraction limit can be obtained. The effects of different polarizing orientations of the linearly polarized incident light on the generation of uniform nanostructures have been investigated by the finite-difference time-domain (FDTD) method. Numerical simulation results show that 1D and/or 2D tunable nanostructures with resolutions beyond diffraction limit can be obtained by controlling the polarizing orientation of the incident light.
