Abstract
A concrete design for an orthogonal polarization rotator at optical frequencies is presented. The subwavelength rotator is formed from a pair of ultrathin metamaterial plates of transparency and remarkable anisotropy. By traveling through the rotator, the incident light of linear polarization undergoes the azimuth-angle rotation by about 90° for a wide range of incident azimuth angles from 0° to 90°. The orthogonal rotator proposed here works with the 1/4 thickness of the incident wavelength and keeps the transmittance as high as 50%, showing a high efficiency as a subwavelength optical element.
