周期场驱动双通道四波混频的竞争与控制
|
摘要
采用密度矩阵方程,分析了倒Y四能级原子系统中相位周期场驱动的双通道四波混频(FWM)过程。数值分析结果表明:周期性相位调制的探测场可以调控两个通道的FWM信号,使之叠加或分离;选择不同的调制频率、调制系数及缀饰场强度,可使FWM信号出现抑制、增强或分裂。这种周期场驱动的调控方法有望用于光学非线性过程的优化及光信息处理。
This study investigates the four-wave mixing(FWM)processes from two channels in an inverted Y-type four-level atomic system driven by aperiodic phase-modulation field using the density matrix equation.The numerical analysis results denote that the FWM signals from the two channels can be controlled to overlap or separate by the probe field with periodic phase modulation.The suppression,enhancement,and splitting of the FWM signals can be observed by selecting different modulation frequencies,modulation coefficients,and dressing field strengths.This FWM control with a periodically driven field can be probably used in the optimization of optical nonlinear processes and the optical information processing.
