Abstract :
We introduced a novel negative multiple pulse poling (NMP) method for uniform device fabrication of quasi-phase matching using an in-situ visualization system. Diffraction pattern analysis showed the duty ratio of 0.42, and the standard deviation of 0.02 which means the uniform quality of the whole poled area.
