论文摘要
从理论上讲，我们研究了剪切应变的半导体中高谐波产生（HHG）的压电效应。通过关注典型的半导体GAA，我们表明存在光学活动，这意味着对右手和左手椭圆极化电场的不同响应。我们还表明，这种光学活性对于高于扰动顺序超过带隙能量的较高谐波更为明显。这些发现指出了非线性光学的应变工程的有用途径，以控制HHG的互惠性。
We theoretically investigate the piezo-optic effect of high-harmonic generation (HHG) in shear-strained semiconductors. By focusing on a typical semiconductor, GaAs, we show that there is optical activity, meaning different responses to right-handed and left-handed elliptically polarized electric fields. We also show that this optical activity is more pronounced for higher harmonics whose perturbative order exceeds the band-gap energy. These findings point to a useful pathway for strain engineering of nonlinear optics to control the reciprocity of HHG.
