| 1 | Boosting anapole-exciton strong coupling in all-dielectric heterostructures显示文摘The light manipulation beyond the diffraction limit plays an invaluable role in modern physics and nanophotonics.In this work,we have demonstrated a strong coupling with a large Rabi splitting of 151 me V between bulk WS_(2)excitons and anapole modes in the WS_(2)-Si nanodisk heterostructure array with nanoholes as small as 50 nm radius.This result is acquired by introducing anapole modes to suppress radiative losses to confine light into subwavelength volumes and large spatial overlapping between excitons and strong optical fields.Our work shows that anapole modes may serve as a powerful way to enhance the interaction between light and matter at nanoscales,and it should pave an avenue toward high-performance all-dielectric optoelectronic applications. | JINGYU WANG WEIMIN YANG GUOYA SUN YONGLIN HE PEIWEN REN ZHILIN YANG | 2022 | Photonics Research2022，10，7： | 0 |
