ABSTRACT:
A periodic poling structure comprises a ferroelectric substrate including a plurality of tunnels, a plurality of first domains positioned in the ferroelectric substrate between the tunnels and a plurality of second domains interleaved between the first domains in the ferroelectric substrate. Each first domain has a first polarization direction, and each second domain has a second polarization direction different from the first polarization direction. The tunnels are disposed on a top surface and on a bottom surface of the ferroelectric substrate in an equal interval manner or in a variant interval manner. Particularly, the second polarization direction is opposite to the first polarization direction. The periodic poling structure further comprises a plurality of conductive blocks covering the entire base surfaces of the tunnels, or separated from the sidewalls of the tunnels by insulation gaps such that the conductive blocks cover only a portion of the base surfaces of the tunnels.
