Abstract
Structurally modulated intrinsic chirality is a structural transformation phenomenon in photoresponsive molecules that is commonly utilized in biosensing and chemical analysis. In this study, we proposed an approach to achieve giant intrinsic chirality in a quasi-bound state in the continuum (Q-BICs)-slanted tetramer metasurface, where high Q factors and circular dichroism (CD) coexist. Empowered by the simultaneous resonance between toroidal dipole (TD) and electric quadrupole (EQ) modes, the intrinsic circular dichroism can be effectively tuned via variations in the slant angles of the metasurface. Our work not only addresses the lack of strong chiral materials in nature but also opens up new possibilities in chiroptical sensing, chemical analysis, and biotechnology.
期刊介绍：
The Optical Society (OSA) publishes high-quality, peer-reviewed articles in its portfolio of journals, which serve the full breadth of the optics and photonics community.
Optics Letters offers rapid dissemination of new results in all areas of optics with short, original, peer-reviewed communications. Optics Letters covers the latest research in optical science, including optical measurements, optical components and devices, atmospheric optics, biomedical optics, Fourier optics, integrated optics, optical processing, optoelectronics, lasers, nonlinear optics, optical storage and holography, optical coherence, polarization, quantum electronics, ultrafast optical phenomena, photonic crystals, and fiber optics. Criteria used in determining acceptability of contributions include newsworthiness to a substantial part of the optics community and the effect of rapid publication on the research of others. This journal, published twice each month, is where readers look for the latest discoveries in optics.
