Quasi-phase-matched multiwave mixing in a periodically poled ferroelectric crystal.
A method for realizing quasi-phase-matched multiwave mixing through second-order nonlinear susceptibilities of a periodically poled ferroelectric crystal is proposed. With an appropriate combination of light polarizations and the order of the quasi-phase-matching, all the nonlinear interactions involved are simultaneously phase matchable. Sample results predicted are shown for five-wave mixing in a periodically poled lithium niobate crystal.
