In a groundbreaking achievement, Chinese scientists have discovered a peculiar behavior in metasurfaces that could potentially revolutionize the field of photonics and quantum mechanics. According to reports, the researchers from the Shenzhen Institute of Advanced Technology at the Chinese Academy of Sciences have successfully slowed down light by more than 10,000 times using a new type of “collective EIT-like resonance.” This remarkable feat surpasses existing methods’ capabilities, offering a promising solution to enhance photonic device performance.
Collective EIT-like Resonance
Dr. LI Guangyuan and his colleagues have introduced a novel strategy to suppress losses associated with slowing down light in metasurfaces. By exploiting the coupling between two collective resonances—an in-plane or out-of-plane electric quadrupole surface lattice resonance (EQ-SLR) and a Mie electric dipole surface lattice resonance (ED-SLR)—they managed to demonstrate collective EIT-like resonances with a quality factor exceeding 2750.
