Abstract
An electrically controlled polarization rotator is disclosed. The electrically controlled polarization rotator includes two substrates and a liquid crystal layer located between the two substrates. The two substrates have a homogeneous alignment and a homeotropic alignment respectively. A distance between the two substrates is a liquid crystal thickness. A switching electric field which is adjustable is provided between the two substrates. A polarized light is incident on the substrate having the homogeneous alignment. A polarization direction of the polarized light is orthogonal or parallel to an alignment direction of the substrate having the homogeneous alignment. A birefringence of the liquid crystal layer multiplied by the liquid crystal thickness and further divided by a wavelength of the polarized light is greater than 10. The polarization direction of the polarized light is rotated corresponding to an intensity of the switching electric field in the liquid crystal layer.
