光学微结构附近原子的巨光移

Giant light shift of atoms near optical microstructures

Peter Horak, Peter Domokos, Helmut Ritsch

摘要:

如果驱动频率接近于微结构的共振和原子跃迁,则耦合到固态微结构中的被限制在一维和二维空间中的光场的原子可以经历非常大的光位移。利用一个简单的准一维波导结构的例子,我们可以解析地计算原子的交流斯塔克位移和原子的存在引起的光场的修改。一个大的增强的有效相互作用强度被发现由于非均匀的模式密度。在实验上,这应该是可见的,通过监测散射光场,以及通过修改从倏逝光反弹的原子轨迹。

英文摘要:

Atoms coupled to optical fields confined in one and two spatial dimensions in solid state microstructures can experience very large light shifts if the driving frequencies are close to a resonance of the microstructures and an atomic transition. Using the simple example of a quasi one-dimensional waveguide structure we can analytically calculate the atomic AC Stark shift and the modifications of the light field induced by the presence of the atom. A large enhancement of the effective interaction strength is found due to a non uniform mode density. Experimentally this should be visible by monitoring the scattered light field as well as by the modification of the atomic trajectories bouncing from the evanescent light.
