我们描述了半导体微腔中受激极化子散射的连续波研究，重点介绍了近年来观察到的各种新物理现象。操纵激子和光子特性的能力，以及它们如何相互作用形成强耦合激子-光子耦合模式，激子极化，导致了许多以前未在体半导体或量子阱中报道的新现象。低极化子分支的不寻常色散，允许在共振激发下能量和动量守恒的极化子-极化子参数散射，被证明是实现许多新物理的关键因素。讨论了这种现象的经典理论处理方法，将受激极化子散射的等效图像与三共振光学参量振荡器的等效图像进行了类比。还描述了高阶参数现象和控制刺激阈值的因素。在谐振激励下得到的结果与在非谐振激励条件下发生的现象进行了对比。讨论了在非共振激励下实现“极化激子激光”的前景。
We describe recent continuous wave studies of stimulated polariton scattering in semiconductor microcavities, with emphasis on the variety of new physics which has been observed in the last few years. The ability to manipulate both exciton and photon properties, and how they interact together to form strongly coupled exciton-photon coupled modes, exciton polaritons, leads to a number of novel phenomena, previously unreported in bulk semiconductors or quantum wells. The unusual dispersion of the lower polariton branch, which allows energy and momentum conserving polariton-polariton parametric scattering under resonant excitation, is shown to be a key factor enabling much of the new physics. A classical theoretical treatment of the phenomena which draws parallels between the equivalent pictures of stimulated polariton scattering and those of a triply resonant optical parametric oscillator is discussed. Higher order parametric phenomena and the factors which control the threshold for stimulation are also described. The results obtained under resonant excitation are contrasted with phenomena which occur under conditions of non-resonant excitation. Prospects to achieve 'polariton lasing' under non-resonant excitation are discussed.
