研究目的
Investigating the lateral and rotary light-drag in semiconductor three-level InAs/GaAs double quantum dot molecules without using any additional coherent laser fields.
研究成果
The study demonstrates that interdot electron tunneling and incoherent pumping can significantly affect the lateral and rotary light-drag in semiconductor quantum dot molecules, offering a method to control light propagation without coherent laser fields.
研究不足
The study is theoretical and does not include experimental validation. The practical implementation of the proposed system may face challenges in controlling the electron tunneling and incoherent pumping rates precisely.
1：Experimental Design and Method Selection:
The study theoretically investigates the effect of interdot electron tunneling and incoherent pumping on light-drag in semiconductor quantum dot molecules.
2：Sample Selection and Data Sources:
The model is based on an asymmetric three-level double quantum dot (DQD) molecule in double layer InAs/GaAs structures.
3：List of Experimental Equipment and Materials:
Not applicable as the study is theoretical.
4：Experimental Procedures and Operational Workflow:
The study uses density matrix equations of motion under the rotating wave approximation to analyze the system's behavior.
5：Data Analysis Methods:
The electric complex susceptibility is calculated to determine the group refractive index and phase refractive index, which are then used to analyze the lateral and rotary light-drag.
