摘要

Plasmonics have enabled the realization of new optical components in nanostructures such as polarizers. We construct nanostructures by polycarbonate grating comprising silver nanospikes prepared by an oblique angle deposition technique. Surface, wavelength, and polarization properties of these devices have been investigated by atomic force microscopy, fiber-coupled spectrometer, and rotating analyzer, respectively. Our results show that we can reach 31 polarization ratio with the aid of two pieces of metalized gratings placed back to back by index-matching gel. Also, we can reach the broadband optical polarizer in the visible region according to the concentration and direction of nanospike in each of metalized nanogratings, which can open up directions toward cheap and one-dimensional optical polarizers.
