Abstract:
A two-dimensional nanowire array with asymmetric lattices was investigated. The orthogonal arrays were fabricated by two-step interference lithography, with 300 nm-pitch arrays overlying the 1000 nm-pitch. Due to the peculiar structure, the properties of the top two-dimensional structure and bottom 1000 nm gratings are superposed. With incidence angles smaller than 30°, short wavelengths of visible light for both transverse electric (TE) and magnetic (TM) polarizations are transmitted as a color filter. For larger incident angles, TE light transmission decreases monotonously, while distinct tunneling of TM light surface plasmon resonance was observed, leading to an integrated polarizer and color filter effect. The experimental results, theoretical calculation, and numerical simulations are in good agreement. The comprehensive characters resulted from the aforementioned mechanisms indicate a new approach to fabricate integrated color filter and polarizer with potential in liquid crystal display, optics communication, and laser applications.
