Abstract

A switchable polarizer includes a transparent layer and switchable material layer. The switchable material layer includes strips of a switchable material that are arranged to polarize incident light propagating through the transparent layer when the switchable material is heated to a threshold switching temperature. The incident light propagating through the transparent layer is unpolarized by the strips of the switchable material when the switchable material is below the threshold switching temperature.
