提出了一种利用电磁诱导透明（EIT）实现（n+1）pod能级相干原子系统中n分量（n > 2）高维超低光孤子Stern-Gerlach效应的方案.从Maxwell-Bloch方程出发，导出了（3+1）维耦合非线性薛定谔方程，描述了n个探测场包络的时空演化.我们表明，在EIT条件下，耦合的超低速光孤子的n个分量的显着偏转可以通过使用Stern-Gerlach梯度磁场实现。通过大失谐激光场的光晶格势可以实现超慢光孤子的稳定性。(C)2013年美国光学学会
We propose a scheme to exhibit a Stern-Gerlach effect of n-component (n > 2) high-dimensional ultraslow optical solitons in a coherent atomic system with (n+1)-pod level configuration via electromagnetically induced transparency (EIT). Based on Maxwell-Bloch equations, we derive coupled (3+1)-dimensional nonlinear Schrdinger equations governing the spatial-temporal evolution of n probe-field envelopes. We show that under EIT conditions significant deflections of the n components of coupled ultraslow optical solitons can be achieved by using a Stern-Gerlach gradient magnetic field. The stability of the ultraslow optical solitons can be realized by an optical lattice potential contributed from a far-detuned laser field. (C) 2013 Optical Society of America
