实验测量了基于多孔硅光子晶体的微腔中产生的二次谐波(SH)的强度与光谱的关系，在腔模附近和光子带隙边缘显示出共振强度的增强(∼2×10~2)。这种增强是由于泵浦辐射在微腔内的局域化、光子晶体中的多重SH干涉以及多孔硅二次极化率在SH频率处的双光子共振共同作用的结果。
The experimental spectral dependence of the intensity of the second harmonic (SH) generated in microcavities based on porous silicon photonic crystal demonstrates resonant intensity enhancement (by a factor of ∼2×102) in the vicinity of the cavity mode and at the edges of the photonic band gap. The enhancement is due to the combined effect of pump radiation localization inside the microcavity, multiple SH interference in the photonic crystal, and two-photon resonance of the porous silicon quadratic susceptibility at the SH frequency.
