We have theoretically demonstrated the efficient generation of nearly flattop ultrabroadband response in a periodic quasiphase matching (QPM) device using a single phase shifter domain. The flat broadband response is generated using optical parametri

A simple nondestructive diffraction method is introduced to estimate the internal electric field present in the congruent lithium niobate crystal. Due to the presence of an unrelaxed internal field, the as-poled sample acts as an index grating and di
