摘要: 对三能级电磁感应透明原子系统的密度矩阵方程进行解算,获得该系统九个密度矩阵元的色散行为,同时研究探针光与控制光所对应的原子气体介电系数的色散曲线和一般相干操控特性。本文将控制光与探针光同等看待,即不同于以往着重于探针光特性、将控制光仅当作调控电磁感应透明介质光学特性的外部条件看待、从而没有研究控制光本身如何受探针光的影响。本文研究探针光与控制光之间的彼此影响(即彼此受对方操控的行为)。电磁感应透明介质内由光来控制光的量子相干行为可以作为新型光子学器件设计的基本原理。
Abstract: The equation of motion of the density matrix of a three-level EIT (electromagnetically induced transparency) atomic system is solved and the behavior of dispersion of the nine density matrix elements is presented. The general optical response of the electric permittivity corresponding to both the probe and the control fields is addressed based on the numerical results of the equation of motion of the density matrix. The probe and the control fields are treated in the same way, in which the influence of the probe field on the control field (and vice versa) is considered. The optical be- havior of controlling light with light can be a fundamental mechanism for new photonic and quantum optical device design.
