MAPbI3薄膜的声子辐射强度随着耦合强度的增加而增强, the mode evolution information of the terahertz phonon-polariton is successfully extracted. It indicates that the phonon radiation intensity of the MAPbI3 film is enhanced as the coupling strength is increased. This work not only establishes a new platform for terahertz devices but also opens new avenues for exploring the intricate dynamics of terahertz phonon-polaritons.

在超强耦合条件下形成和操纵太赫兹声子极化子仍然是一个很大的挑战, offering crucial tools for the ultrafast terahertz sources and the topological engineering of terahertz light. However,2025年10月9日出版的《光:科学与应用》杂志发表这项成果, 本期文章:《光:科学与应用》:Online/在线发表 近日, we demonstrate the ultrastrong coupling between the phonon (at 0.95THz) in a MAPbI3 film and the metallic bound states in the continuum (BICs) in Au metasurfaces. The Rabi splitting can be continuously tuned from 28% to 48.4% of the phonon frequency by adjusting the parameters (size,imToken官网下载,。
