## Description

- description: Optical microcavities provide a powerful and versatile framework for
    manipulating the dynamics of photonic emission from optically active materials
    through light recirculation. Spatially indirect interlayer excitons (IXs) exhibit
    broad tunability of their emission energy via the quantum-confined Stark effect.
    However, the electrical tunability of IXs has not been exploited in cavity-coupled
    systems until now. In this work, we modulate the detuning between the cavity resonance
    and the IX emission in a monolithic Fabry-Perot cavity using an applied vertical
    electric field. We reveal a simultaneous enhancement of both the emission intensity
    and lifetime of weakly-coupled IXs when in resonance with the optical cavity due
    to strong Purcell inhibition and cavity transparency effects. We further investigate
    the tunable momentum dispersion of coupled IXs through back-focal plane imaging
    and explain our results by the cavity coupling of IX transition dipoles as supported
    by theoretical modeling. Our work represents an unprecedented integration effort
    that enables the versatile tuning of highly interacting IXs within monolithic
    cavities, revealing the attractiveness of electrically tunable IX cavity coupling
    for both fundamental studies towards exciton condensate manipulation and future
    integration of excitonic devices.
