激子跃迁与电磁模式的强耦合导致称为激子极化激元的复合准粒子,其已被证明联合收割机结合了半导体微腔中其单个组分的最佳性质。然而,由于这种结构中光子的限制性很差,因此在有机材料中和室温下极化激元流的物理和应用仍然没有得到探索。在这里,我们证明了由有机激子与布洛赫表面波的杂交形成的极化激元能够传播数百微米,在高注入密度时表现出显着的三阶非线性相互作用。这些发现为有机非线性光物质通量的研究和实现在室温下工作的无耗散片上极化激元器件的技术路线铺平了道路。
The strong coupling of an excitonic transition with an electromagnetic mode results in composite quasi-particles called exciton polaritons, which have been shown to combine the best properties of their individual components in semiconductor microcavities. However, the physics and applications of polariton flows in organic materials and at room temperature are still unexplored because of the poor photon confinement in such structures. Here, we demonstrate that polaritons formed by the hybridization of organic excitons with a Bloch surface wave are able to propagate for hundreds of microns showing remarkable third-order nonlinear interactions upon high injection density. These findings pave the way for the study of organic nonlinear light–matter fluxes and for a technologically promising route of the realization of dissipation-less on-chip polariton devices operating at room temperature.
