The angular-tuning and temperature-dependent analyses suggest a quasi-phase-matching mechanism from a unique dispersion of reciprocal vectors in the rectangular lattice structure.Dispersion-activated QPM-SHG in two-dimensional periodically poled LiNbO3conference paper2-s2.0-85136244681https://api.elsevier.com/content/abstract/scopus_id/85136244681
