Abstract The manipulation of exciton–polaritons and their condensates is great interest due to applications in polariton simulators high‐speed, all‐optical logic devices. Until now, methods trapping manipulating such are not dynamically reconfigurable or resulted an undesirable reduction the exciton–photon coupling strength. Here, a new strategy for ultrafast control resonances via transient modification optical cavity mode presented. Multilayer organic semiconductor microcavities that contain two absorbers constructed: one strongly‐coupled photon out‐of‐resonance. By selectively exciting out‐of‐resonance absorber using ultrashort laser pulses, refractive index modulated, fully‐reversible blueshifts lower branch by up 8 meV sub‐ps timescales with no corresponding strength generated. This work demonstrates ability manipulate energy landscapes over important emerging computing technologies.
