| contents | In this study, optically responsive exciton-polariton were generated via strong coupling between DR1 molecules and an F-P microcavity. An electromagnetically induced grating (EIG) was constructed using two-beam interference to investigate EP modulation effects.EP formation was confirmed by transmission spectroscopy, angle-dependent measurements, and k-space reflection. Rabi splitting increased with DR1 concentration, indicating enhanced light-matter interaction. Under 532 nm laser illumination, reversible Rabi splitting changes occurred: upper/lower polariton peaks shifted by 16 nm-8 nm toward the 490 nm absorption peak with a 2% transmittance increase, recovering after laser removal.Introducing EP into EIG enhanced first-order diffraction intensity by 2-10 times compared to the non-coupled state, with peak positions shifting 8-30 nm under EP regulation. Diffraction angles varied within 2°, correlating with coupling strength. Compared with the bare DR1/PMMA film, the EIG diffraction signal of the strong coupling device was 2-7 times stronger, with clearer resolution and faster optical response near the resonance position, attributed to the enhanced light-matter interaction in the EP system. |
