Abstract
A light control device is formed by ferroelectric material and N electrodes positioned adjacent thereto to define an N-sided regular polygonal region or circular region therebetween where N is a multiple of four.
Claims15
A light control device, comprising:
- a layer of ferroelectric material having first and second planar surfaces opposing one another;
- and
- a plurality of electrodes positioned adjacent to said first planar surface and electrically isolated from one another to define an N-sided region therebetween where N is a multiple of 4.
A light control device comprising at least one multi-layer element defined by a layer of ferroelectric material and a layer of electrodes coupled to said layer of ferroelectric material, said layer of electrodes comprising N electrodes electrically isolated from one another and positioned to define a regularly-shaped region therebetween where N is a multiple of 4.
A light control device as in claim/wherein said layer of ferroelectric material is of constant thickness.
A light control device, comprising:
- a layer of ferroelectric material of constant thickness having first and second planar surfaces opposing one another;
- and
- means coupled to said first planar surface for establishing an electric field orientation adjacent to an exposed region of said ferroelectric material wherein said electric field orientation and said constant thickness of said ferroelectric material define optical transmission properties for said exposed region.
