In this paper, the polarization angle of intense laser field and incident light effects on the intersubband optical absorption and refractive index change in the square quantum well wire are investigated theoretically by Kramers–Henneberger approximation. It is found that the polarization angle of the intense laser field can influence the energy gap and exchange electronic configuration by breaking symmetry. Hence, the incident light polarization angle should be considered. The variation of optical absorption and refractive index change are given with different polarization-intense laser fields and probe light, which provides the possibility of designing various polarization-sensitive devices.

强激光场不同偏振作用下方形量子阱线的各向异性光学特性

本文通过Kramers-Henneberger近似从理论上研究了强激光场的偏振角和入射光对方形量子阱线中子带间光吸收和折射率变化的影响。发现强激光场的偏振角可以通过破坏对称性来影响能隙和交换电子配置。因此,应考虑入射光偏振角。不同的偏振强度激光场和探测光给出了光吸收和折射率变化的变化,这为设计各种偏振敏感器件提供了可能。
