Abstract
An optical phase controller includes an optical phase control element so that a phase of incident light applied to the optical phase control element is controlled. The optical phase control element includes a metal structure having anisotropy in a first direction and a second direction perpendicular to the first direction within an electric-field vibration plane of the incident light, the wavelength of the incident light includes a plasmon resonance wavelength possessed by the metal structure, and the incident light is linearly polarized light or elliptically polarized light simultaneously having polarized components in the first direction and the second direction perpendicular to the first direction.
