Electronic Light-Matter Strong Coupling in Nanofluidic Fabry-Pérot Cavities

• Electronic light-matter strong coupling has been limited to solid molecular films due to the challenge of preparing optical cavities with nanoscale dimensions. Here we report a technique to fabricate such Fabry-Pérot nanocavities in which solutions can be introduced such that light-molecule interactions can be studied at will in the liquid phase. We illustrate the versatility of these cavities by studying the emission properties of Chlorin e6 solutions in both the weak and strong coupling regimes as a function of cavity detuning. Liquid nanocavities will broaden the investigation of strong coupling to many solution-based molecular processes. © 2017 American Chemical Society.
