非线性介质中的极化子谱

Polariton spectrum in nonlinear dielectric medium

Igor V. Dzedolik, O. Karakchieva

摘要:

从理论上得到了三阶克尔型非线性介质中的声子极化激元谱。研究了极化激元谱分支数目与电磁场强度的关系,证明了位于极化激元谱隙中的新分支的出现是由于介质中三阶介电极化率在强场处的色散的影响。新分支波的调制不稳定性导致椭圆余弦波和孤子的出现。

英文摘要:

We obtain theoretically the phonon-polariton spectrum in nonlinear dielectric medium with the third order Kerr-type nonlinearity. We investigate the dependence of number of the polariton spectrum branches on the intensity of electromagnetic field and demonstrate that the appearance of new branches located in the polariton spectrum gap is caused by the influence of dispersion of the third order dielectric susceptibility at intensity field in the medium. The modulation instability of new branch waves leading to appearance of cnoidal waves and solitons.
