Abstract
We report experimental and numerical studies of a polarization conversion by a three-dimensional photonic crystal. The (001) surface of a photonic crystal with a diamond structure has been shown to act as a mirror-type polarization convertor under normal incidence. When the direction of the incident wave polarization is along [010], the direction of the reflected wave polarization is converted to [100]. This has been found to be due to approximately a half-wave phase shift between the eigenpolarizations of [110] and [1 1¯ 0] upon reflection. This result has been discussed in relation with a polarization-dependent Goos–Haenchen effect.
