Abstract
Quasi-phase-matching (QPM) is an alterative approach for nonlinear optical frequency conversion compared to conventional birefringent method in the bulk crystal. In this Letter, two-dimensional aperiodic optical superlattice (2DAOS) for achieving multi-QPM is proposed. A special optical superlattice structure containing pre-designed values of the reciprocal lattice vector G that can accomplish multi-QPM process is given by using stimulated annealing (SA) algorithm.
