论文摘要
我们研究了在散装Kerr培养基中的非椭圆极化的光传播的非椭圆极化流体中，固有的自旋轨道耦合与非线性光子光子相互作用之间的相互作用。我们发现，在非线性相互作用会引起双极性依赖性的非线性非线性折射率的情况下，它们与自旋轨道耦合的相互作用会导致流体在不同波矢量上行进的两个极化成分之间的干扰，从而导致了沿着沿propagationsementry Stiressiontrysmetrationsmetration Semprogationsementrysementrysementrysementrysightionsmetrationsmetration Symetration rypagationsementry symetration rypagationsementrysightion respagationsions。这种现象导致流体的Bogoliubov光谱中的浮雕带结构，并导致其强度相关性的特征振荡。我们详细表征了这些振荡，并指出了它们在大传播距离处的指数生长，从而揭示了参数共振的存在。
We study the interplay between intrinsic spin-orbit coupling and nonlinear photon-photon interactions in a nonparaxial, elliptically polarized fluid of light propagating in a bulk Kerr medium. We find that in situations where the nonlinear interactions induce birefringence, i.e., a polarization-dependent nonlinear refractive index, their interplay with spin-orbit coupling results in an interference between the two polarization components of the fluid traveling at different wave vectors, which entails the breaking of translation symmetry along the propagation direction. This phenomenon leads to a Floquet band structure in the Bogoliubov spectrum of the fluid, and to characteristic oscillations of its intensity correlations. We characterize these oscillations in detail and point out their exponential growth at large propagation distances, revealing the presence of parametric resonances.
