Strong light–matter coupling is achieved by placing an atomically thin WS₂ monolayer in a Fabry–Pérot cavity configuration. Herein, a multilayer approach is adapted for fine tuning the position of the active layer within the cavity. This allows the control of light–matter interaction between the active layer and the cavity photon. Moving the monolayer in the confined volume shows a clear field dependence, as reflected in their Rabi splitting energy. These are again confirmed by angle‐resolved transmission and photoluminescence measurements. A large drop in the effective mass is observed for polaritonic states formed at the antinode of the cavity, suggesting its potential applications in energy/electron transport.

WS2单层中强耦合的电磁场依赖性

通过在Fabry-Pérot腔配置中放置原子薄的WS ₂单层，可以实现强大的光-质耦合。在本文中，多层方法适于微调腔内有源层的位置。这样可以控制有源层和腔体光子之间的光-物质相互作用。在约束体积中移动单分子层显示出明显的场依赖性，这反映在它们的拉比分裂能上。角度分辨透射和光致发光测量再次证实了这些。对于在腔的波腹处形成的极化子态，观察到有效质量的大幅下降，表明其在能量/电子传输中的潜在应用。
