When do molecular polaritons behave like optical filters?

Chem. Soc. Rev., 2025, Advance Article DOI: 10.1039/D4CS01024H, Review Article Kai Schwennicke, Arghadip Koner, Juan B. Pérez-Sánchez, Wei Xiong, Noel C. Giebink, Marissa L. Weichman, Joel Yuen-Zhou This review outlines under what circumstances molecular polaritons act, in part, as optical filters. When these circumstances are met, the “polaritonic” phenomena can generally be explained via the principles of linear optics.
