摘要/Abstract

摘要：利用Zubarev’s格林函数方法研究了强太赫兹电场作用下微腔中的双量子阱激子光吸收特性.将腔场和太赫兹场处理为光子，根据哈密顿量得到运动方程.研究考虑了失谐、太赫兹场耦合常数以及电子数的衰减率.研究发现，在强太赫兹场作用时，光谱呈现丰富的非线性效应，如出现复制峰和Autler-Townes分裂.该研究为微腔-量子阱系统量子光学响应提供了一个简单、方便的全量子理论处理方法.

关键词： 光吸收, 强太赫兹电场, Autler-Townes分裂

Abstract: An approach of solving excitonic absorption is presented for an asymmetric double quantum well driven by an intense terahertz field embedded in a semiconductor microcavity.The formalism relies on Zubarev’s Green functions,which allow us to handle the microcavity field and terahertz field as the photons and to fully account for the quantum aspect of the optical response of the asymmetric double quantum wells.Rich nonlinear dynamics behaviors of the replica peak and the Autler-Townes splitting are systematically studied in undoped asymmetric double quantum wells for taking account of the multiple factors,such as the detuning,coupling constant of the intense terahertz field,decay rate of the second electron subband,photon number of the intense terahertz field.The work provides a simple and convenient approach to deal with the microcavity-optical response of the asymmetric double quantum well in a fully quantum mechanical framework.
