Abstract

We proposed and experimentally demonstrated the polarization-controlled dual-band optical transmission through metallic hole array. It is utilized the anisotropic enhanced transmission through metallic array of subwavelength rectangular holes. The meaning is that the incident polarization state can decide the output wavelength. Two polarization-manipulated resonant transmissions at 632 nm (red) and 532 nm (green) have been demonstrated. It can be applied for achieving integrated polarization-controlled red-green light switching devices. Also, it can be used as a wavelength-dependent micropolarizer.
