Abstract

A light modulator (100) comprises a plurality of discrete variable transmission electro-optic layers (106, 120, 128) arranged so that light will pass successively through the plurality of layers (106, 120, 128); the light modulator (100) has a higher transmission range than any of the individual electro-optic layers (106, 120, 128) separately.
