Nonlinear photonic crystals formed by two-dimensional periodic poling of the quadratic susceptibility chi(2) can support quasi-phase-matched harmonic generation. The frequency-conversion efficiency depends on the photonic crystal's poling pattern through certain Fourier coefficients of the poling function. A procedure is described for finding those poling patterns that are most efficient for any specific quasi-phase-matched frequency-conversion scheme.
通过二次极化率χ(2)的二维周期性极化形成的非线性光子晶体能够支持准相位匹配谐波产生。频率转换效率通过极化函数的某些傅里叶系数取决于光子晶体的极化图案。本文描述了一种用于找到对于任何特定准相位匹配频率转换方案最有效的极化图案的方法。
