Abstract Transition metal dichalcogenides integrated within a high-quality microcavity support well-defined exciton polaritons. While the role of intralayer excitons in 2D polaritonics is well studied, interlayer have been largely ignored due to their weak oscillator strength. Using microscopic and material-realistic Wannier–Hopfield model, we demonstrate that MoS 2 homobilayers Fabry–Perot cavity polaritons exhibit large contribution, while remaining visible linear optical spectra. Interestingly, with suitable tuning length, hybridization between intra- can be ‘unmixed’ interaction photons. We predict formation where > 90 % total excitonic contribution stemming from exciton. Furthermore, explore conditions on tunneling strength energy landscape push this 100%. Despite extremely underlying exciton, effectively fed into once critical coupling condition balanced radiative scattering decay channels met. These findings wide relevance for fields ranging nonlinear optoelectronic devices Bose–Einstein condensation.
