Polaritons are quasi-particles composed of a superposition of excitons and photons that can be created within a strongly coupled optical microcavity. Here, we describe a structure in which a strongly coupled microcavity containing an organic semiconductor is coupled to a second microcavity containing a series of weakly coupled inorganic quantum wells. We show that optical hybridisation occurs between the optical modes of the two cavities, creating a delocalised polaritonic state. By electrically injecting electron–hole pairs into the inorganic quantum-well system, we are able to transfer energy between the cavities and populate organic-exciton polaritons. Our approach represents a new strategy to create highly efficient devices for emerging ‘polaritonic’ technologies.

极化子是由激子和光子的叠加组成的准粒子，可以在强耦合的光学微腔中产生。在这里，我们描述了一种结构，其中包含有机半导体的强耦合微腔耦合到包含一系列弱耦合无机量子阱的第二微腔。我们显示光学杂交发生在两个腔的光学模式之间，从而产生离域的极化状态。通过将电子-空穴对电注入到无机量子阱系统中，我们能够在腔之间转移能量并填充有机激子极化子。我们的方法代表了一种为新兴的“极化声”技术创建高效设备的新策略。
