Abstract
In this paper wave-coupling equations including polarization coupling and frequency doubling in periodically poled lithium niobate (PPLN) is proposed. Numerical solutions of the coupling equations show that there is a competition between the polarization coupling and second-harmonic generation in a PPLN under the phase-matching condition. The influences of the external electric field on the polarizations and amplitudes of three interactive waves are studied.
