Abstract

An optical dimming device includes at least one polarization rotator configured to switch a polarization of a linearly polarized component of an incoming light between two orthogonal polarizations. The optical dimming device also includes at least one polarizer coupled with the at least one polarization rotator, and configured to output a light having a light intensity reduced to a predetermined percentage of an initial light intensity of the incoming light. The predetermined percentage is substantially the same for different incoming lights having different initial polarizations.
