Abstract
Liquid crystal modulator optical devices and more specifically shutters and smart windows are presented. The liquid crystal modulator devices are characterized by a reduced polymer content which is eliminated from the material composition of the liquid crystal layer and characterized by non-uniform electrode structures in the liquid crystal structure configured to generate spatially non-uniform electric fields and therefore non-uniform molecular reorientation of liquid crystal molecules. This arrangement advantageously makes light scattering electrically controllable.
