摘要

研究了各向异性非线性电介质二元层周期叠加产生的组合频率。用三波混频过程来描述非线性散射的产物。结果表明，各向异性层的本构参数和几何参数以及泵浦波的频率比和入射角对组合频率散射波的强度有很大的影响。在无损和有损层状结构中，提高了Wolf-Bragg共振的频率转换效率。

Nonlinear Scattering by Anisotropic Dielectric Periodic Structures

The combinatorial frequency generation by the periodic stacks of binary layers of anisotropic nonlinear dielectrics is examined. The products of nonlinear scattering are characterised in terms of the three-wave mixing processes. It is shown that the intensity of the scattered waves of combinatorial frequencies is strongly influenced by the constitutive and geometrical parameters of the anisotropic layers, and the frequency ratio and angles of incidence of pump waves. The enhanced efficiency of the frequency conversion at Wolf-Bragg resonances has been demonstrated for the lossless and lossy-layered structures.
