应用Pegg-Barnett相位理论,研究了隧穿量子点分子模型与光场相互作用系统中光场的相位特性,着重分析了光场的相位概率分布及相位涨落,并讨论了平均光子数和失谐量以及时间对相位概率分布的影响.结果发现:光场相位概率分布在零附近的概率分布最大,且涨落最小,而其它范围内概率分布小且容易振荡,适当调节平均光子数和时间,能使相位概率分布由单峰结构向对称的三峰高斯分布转化,且能调节峰值的大小. The Pegg-Barnett phase theory is used to study the phase characteristics of the light field in the quantum dot interaction model and the optical field. The phase probability distribution and the phase fluctuation of the light field are analyzed emphatically. The average photon number and the loss The results show that the probability distribution of the phase field in the light field has the largest probability distribution and the least fluctuation, while the other areas have a small probability distribution and easy oscillation. The average photon number and the time , The phase probability distribution can be transformed from a unimodal structure to a symmetrical three-peak Gaussian distribution, and the peak size can be adjusted.
