Abstract
A poled structure comprises a ferroelectric substrate having a top surface and a bottom surface, at least one inhibition block positioned in the ferroelectric substrate, an electrode structure including a first electrode and a second electrode on the top surface and a third electrode in a portion of the bottom surface between the first electrode and the second electrode and a plurality of inverted domains positioned outside of the inhibition block in the ferroelectric substrate. The ferroelectric substrate has a first polarization direction and a first crystal structure, the inhibition block has a second crystal structure different from the first crystal structure, and the inverted domains has a second polarization direction substantially opposite to the first polarization direction.
