Two-dimensional materials support deeply confined and tunable plasmonicmodes, which have great potential for achieving device miniaturization andflexible manipulation. In this paper, we propose a diffraction-unlimited systemcomposed of borophene layer and perovskite grating to investigate the strongcoupling between the borophene guiding plasmon (BGP) and perovskite exciton(PE) mode. The resonant energy of BGP mode could be electrically tuned to matchthe energy of PE mode, and a remarkable Rabi splitting is attained underzero-detuning condition. The splitting energy could reach 230 meV due to thestrong field enhancement provided by BGP mode. Consequently, an activereflective phase modulation with 1.76{\pi} range is achieved by dynamicallymanipulating the detuning. Furthermore, by increasing the distance between theborophene layer and perovskite grating, a parity-time symmetry breaking couldbe observed with the vanished energy splitting. Our results deepen theunderstanding of light-matter interaction at the sub-wavelength scale andprovide a guideline for designing active plasmonic devices.
