Fabrication of patterned poled dielectric structures and devices

摘要: A poled dielectric substrate is fabricated by creating a uniform potential, such as ground means of an electrode surface, adjacent first surface polable material (6), piezoelectric or lithium niobate, and then applying electric field (20) second the (8), where spatially-modulated according to three-dimensional modulation pattern with amplitude level at selected locations sufficient cause atomic rearrangement within predefined regions in material, controlled parameter. The control mechanism may be protrusions electrically conductive (15) extending toward modulated variation constant separating from plate.
