论文摘要
激子 - 果龙是由光子模式的非扰动耦合和激子共振引起的杂交光 - 物质激发。它们表现为相互作用的光子，它们显示出光学的三阶非线性，提供了诸如光学参数振荡或放大之类的效果。有人提出，通过在其激子部分中诱导对齐的电偶极子，可以极大地增强北极星的相互作用。然而，直接证据表明了真正的颗粒粒子相互作用，例如超流体或参数散射。在这项工作中，我们证明了偶极相互作用可用于增强参数效应，例如波导极性子中的自相度调制。通过量化这些光学非线性，我们提供了可靠的实验测量，可对北极星相互作用的直接偶极增强。
Exciton-polaritons are hybrid light-matter excitations arising from the non-perturbative coupling of a photonic mode and an excitonic resonance. Behaving as interacting photons, they show optical third-order nonlinearities providing effects such as optical parametric oscillation or amplification. It has been suggested that polariton-polariton interactions can be greatly enhanced by inducing aligned electric dipoles in their excitonic part. However direct evidence of a true particle-particle interaction, such as superfluidity or parametric scattering is still missing. In this work, we demonstrate that dipolar interactions can be used to enhance parametric effects such as self-phase modulation in waveguide polaritons. By quantifying these optical nonlinearities we provide a reliable experimental measurement of the direct dipolar enhancement of polariton-polariton interactions.
